How to Write a Research Question: Types and Examples 

research quetsion

The first step in any research project is framing the research question. It can be considered the core of any systematic investigation as the research outcomes are tied to asking the right questions. Thus, this primary interrogation point sets the pace for your research as it helps collect relevant and insightful information that ultimately influences your work.   

Typically, the research question guides the stages of inquiry, analysis, and reporting. Depending on the use of quantifiable or quantitative data, research questions are broadly categorized into quantitative or qualitative research questions. Both types of research questions can be used independently or together, considering the overall focus and objectives of your research.  

What is a research question?

A research question is a clear, focused, concise, and arguable question on which your research and writing are centered. 1 It states various aspects of the study, including the population and variables to be studied and the problem the study addresses. These questions also set the boundaries of the study, ensuring cohesion. 

Designing the research question is a dynamic process where the researcher can change or refine the research question as they review related literature and develop a framework for the study. Depending on the scale of your research, the study can include single or multiple research questions. 

A good research question has the following features: 

  • It is relevant to the chosen field of study. 
  • The question posed is arguable and open for debate, requiring synthesizing and analysis of ideas. 
  • It is focused and concisely framed. 
  • A feasible solution is possible within the given practical constraint and timeframe. 

A poorly formulated research question poses several risks. 1   

  • Researchers can adopt an erroneous design. 
  • It can create confusion and hinder the thought process, including developing a clear protocol.  
  • It can jeopardize publication efforts.  
  • It causes difficulty in determining the relevance of the study findings.  
  • It causes difficulty in whether the study fulfils the inclusion criteria for systematic review and meta-analysis. This creates challenges in determining whether additional studies or data collection is needed to answer the question.  
  • Readers may fail to understand the objective of the study. This reduces the likelihood of the study being cited by others. 

Now that you know “What is a research question?”, let’s look at the different types of research questions. 

Types of research questions

Depending on the type of research to be done, research questions can be classified broadly into quantitative, qualitative, or mixed-methods studies. Knowing the type of research helps determine the best type of research question that reflects the direction and epistemological underpinnings of your research. 

The structure and wording of quantitative 2 and qualitative research 3 questions differ significantly. The quantitative study looks at causal relationships, whereas the qualitative study aims at exploring a phenomenon. 

  • Quantitative research questions:  
  • Seeks to investigate social, familial, or educational experiences or processes in a particular context and/or location.  
  • Answers ‘how,’ ‘what,’ or ‘why’ questions. 
  • Investigates connections, relations, or comparisons between independent and dependent variables. 

Quantitative research questions can be further categorized into descriptive, comparative, and relationship, as explained in the Table below. 

  • Qualitative research questions  

Qualitative research questions are adaptable, non-directional, and more flexible. It concerns broad areas of research or more specific areas of study to discover, explain, or explore a phenomenon. These are further classified as follows: 

  • Mixed-methods studies  

Mixed-methods studies use both quantitative and qualitative research questions to answer your research question. Mixed methods provide a complete picture than standalone quantitative or qualitative research, as it integrates the benefits of both methods. Mixed methods research is often used in multidisciplinary settings and complex situational or societal research, especially in the behavioral, health, and social science fields. 

What makes a good research question

A good research question should be clear and focused to guide your research. It should synthesize multiple sources to present your unique argument, and should ideally be something that you are interested in. But avoid questions that can be answered in a few factual statements. The following are the main attributes of a good research question. 

  • Specific: The research question should not be a fishing expedition performed in the hopes that some new information will be found that will benefit the researcher. The central research question should work with your research problem to keep your work focused. If using multiple questions, they should all tie back to the central aim. 
  • Measurable: The research question must be answerable using quantitative and/or qualitative data or from scholarly sources to develop your research question. If such data is impossible to access, it is better to rethink your question. 
  • Attainable: Ensure you have enough time and resources to do all research required to answer your question. If it seems you will not be able to gain access to the data you need, consider narrowing down your question to be more specific. 
  • You have the expertise 
  • You have the equipment and resources 
  • Realistic: Developing your research question should be based on initial reading about your topic. It should focus on addressing a problem or gap in the existing knowledge in your field or discipline. 
  • Based on some sort of rational physics 
  • Can be done in a reasonable time frame 
  • Timely: The research question should contribute to an existing and current debate in your field or in society at large. It should produce knowledge that future researchers or practitioners can later build on. 
  • Novel 
  • Based on current technologies. 
  • Important to answer current problems or concerns. 
  • Lead to new directions. 
  • Important: Your question should have some aspect of originality. Incremental research is as important as exploring disruptive technologies. For example, you can focus on a specific location or explore a new angle. 
  • Meaningful whether the answer is “Yes” or “No.” Closed-ended, yes/no questions are too simple to work as good research questions. Such questions do not provide enough scope for robust investigation and discussion. A good research question requires original data, synthesis of multiple sources, and original interpretation and argumentation before providing an answer. 

Steps for developing a good research question

The importance of research questions cannot be understated. When drafting a research question, use the following frameworks to guide the components of your question to ease the process. 4  

  • Determine the requirements: Before constructing a good research question, set your research requirements. What is the purpose? Is it descriptive, comparative, or explorative research? Determining the research aim will help you choose the most appropriate topic and word your question appropriately. 
  • Select a broad research topic: Identify a broader subject area of interest that requires investigation. Techniques such as brainstorming or concept mapping can help identify relevant connections and themes within a broad research topic. For example, how to learn and help students learn. 
  • Perform preliminary investigation: Preliminary research is needed to obtain up-to-date and relevant knowledge on your topic. It also helps identify issues currently being discussed from which information gaps can be identified. 
  • Narrow your focus: Narrow the scope and focus of your research to a specific niche. This involves focusing on gaps in existing knowledge or recent literature or extending or complementing the findings of existing literature. Another approach involves constructing strong research questions that challenge your views or knowledge of the area of study (Example: Is learning consistent with the existing learning theory and research). 
  • Identify the research problem: Once the research question has been framed, one should evaluate it. This is to realize the importance of the research questions and if there is a need for more revising (Example: How do your beliefs on learning theory and research impact your instructional practices).

Research questions lie at the core of systematic investigation and this is because recording accurate research outcomes is tied to asking the right questions. Asking the right questions when conducting research can help you collect relevant and insightful information that ultimately influences your work, positively. 

The right research questions are typically easy to understand, straight to the point, and engaging. In this article, we will share tips on how to create the right research questions and also show you how to create and administer an online questionnaire with Formplus . 

What is a Research Question? 

A research question is a specific inquiry which the research seeks to provide a response to. It resides at the core of systematic investigation and it helps you to clearly define a path for the research process. 

A research question is usually the first step in any research project. Basically, it is the primary interrogation point of your research and it sets the pace for your work.  

Typically, a research question focuses on the research, determines the methodology and hypothesis, and guides all stages of inquiry, analysis, and reporting. With the right research questions, you will be able to gather useful information for your investigation. 

Types of Research Questions 

Research questions are broadly categorized into 2; that is, qualitative research questions and quantitative research questions. Qualitative and quantitative research questions can be used independently and co-dependently in line with the overall focus and objectives of your research. 

If your research aims at collecting quantifiable data , you will need to make use of quantitative research questions. On the other hand, qualitative questions help you to gather qualitative data bothering on the perceptions and observations of your research subjects. 

Qualitative Research Questions  

A qualitative research question is a type of systematic inquiry that aims at collecting qualitative data from research subjects. The aim of qualitative research questions is to gather non-statistical information pertaining to the experiences, observations, and perceptions of the research subjects in line with the objectives of the investigation. 

Types of Qualitative Research Questions  

  • Ethnographic Research Questions

As the name clearly suggests, ethnographic research questions are inquiries presented in ethnographic research. Ethnographic research is a qualitative research approach that involves observing variables in their natural environments or habitats in order to arrive at objective research outcomes. 

These research questions help the researcher to gather insights into the habits, dispositions, perceptions, and behaviors of research subjects as they interact in specific environments. 

Ethnographic research questions can be used in education, business, medicine, and other fields of study, and they are very useful in contexts aimed at collecting in-depth and specific information that are peculiar to research variables. For instance, asking educational ethnographic research questions can help you understand how pedagogy affects classroom relations and behaviors. 

This type of research question can be administered physically through one-on-one interviews, naturalism (live and work), and participant observation methods. Alternatively, the researcher can ask ethnographic research questions via online surveys and questionnaires created with Formplus.  

Examples of Ethnographic Research Questions

  • Why do you use this product?
  • Have you noticed any side effects since you started using this drug?
  • Does this product meet your needs?

ethnographic-research-questions

  • Case Studies

A case study is a qualitative research approach that involves carrying out a detailed investigation into a research subject(s) or variable(s). In the course of a case study, the researcher gathers a range of data from multiple sources of information via different data collection methods, and over a period of time. 

The aim of a case study is to analyze specific issues within definite contexts and arrive at detailed research subject analyses by asking the right questions. This research method can be explanatory, descriptive , or exploratory depending on the focus of your systematic investigation or research. 

An explanatory case study is one that seeks to gather information on the causes of real-life occurrences. This type of case study uses “how” and “why” questions in order to gather valid information about the causative factors of an event. 

Descriptive case studies are typically used in business researches, and they aim at analyzing the impact of changing market dynamics on businesses. On the other hand, exploratory case studies aim at providing answers to “who” and “what” questions using data collection tools like interviews and questionnaires. 

Some questions you can include in your case studies are: 

  • Why did you choose our services?
  • How has this policy affected your business output?
  • What benefits have you recorded since you started using our product?

case-study-example

An interview is a qualitative research method that involves asking respondents a series of questions in order to gather information about a research subject. Interview questions can be close-ended or open-ended , and they prompt participants to provide valid information that is useful to the research. 

An interview may also be structured, semi-structured , or unstructured , and this further influences the types of questions they include. Structured interviews are made up of more close-ended questions because they aim at gathering quantitative data while unstructured interviews consist, primarily, of open-ended questions that allow the researcher to collect qualitative information from respondents. 

You can conduct interview research by scheduling a physical meeting with respondents, through a telephone conversation, and via digital media and video conferencing platforms like Skype and Zoom. Alternatively, you can use Formplus surveys and questionnaires for your interview. 

Examples of interview questions include: 

  • What challenges did you face while using our product?
  • What specific needs did our product meet?
  • What would you like us to improve our service delivery?

Quantitative Research Questions

Quantitative research questions are questions that are used to gather quantifiable data from research subjects. These types of research questions are usually more specific and direct because they aim at collecting information that can be measured; that is, statistical information. 

Types of Quantitative Research Questions

  • Descriptive Research Questions

Descriptive research questions are inquiries that researchers use to gather quantifiable data about the attributes and characteristics of research subjects. These types of questions primarily seek responses that reveal existing patterns in the nature of the research subjects. 

It is important to note that descriptive research questions are not concerned with the causative factors of the discovered attributes and characteristics. Rather, they focus on the “what”; that is, describing the subject of the research without paying attention to the reasons for its occurrence. 

Descriptive research questions are typically closed-ended because they aim at gathering definite and specific responses from research participants. Also, they can be used in customer experience surveys and market research to collect information about target markets and consumer behaviors. 

Descriptive Research Question Examples

  • How often do you make use of our fitness application?
  • How much would you be willing to pay for this product?

descriptive-research-question

  • Comparative Research Questions

A comparative research question is a type of quantitative research question that is used to gather information about the differences between two or more research subjects across different variables. These types of questions help the researcher to identify distinct features that mark one research subject from the other while highlighting existing similarities. 

Asking comparative research questions in market research surveys can provide insights on how your product or service matches its competitors. In addition, it can help you to identify the strengths and weaknesses of your product for a better competitive advantage.  

The 5 steps involved in the framing of comparative research questions are: 

  • Choose your starting phrase
  • Identify and name the dependent variable
  • Identify the groups you are interested in
  • Identify the appropriate adjoining text
  • Write out the comparative research question

Comparative Research Question Samples 

  • What are the differences between a landline telephone and a smartphone?
  • What are the differences between work-from-home and on-site operations?

comparative-research-question

  • Relationship-based Research Questions  

Just like the name suggests, a relationship-based research question is one that inquires into the nature of the association between two research subjects within the same demographic. These types of research questions help you to gather information pertaining to the nature of the association between two research variables. 

Relationship-based research questions are also known as correlational research questions because they seek to clearly identify the link between 2 variables.

Examples of relationship-based research questions include: 

  • What is the relationship between purchasing power and the business site?
  • What is the relationship between the work environment and workforce turnover?

Examples of a Good Research Question

Since research questions lie at the core of any systematic investigations, it is important to know how to frame a good research question. The right research questions will help you to gather the most objective responses that are useful to your systematic investigation. 

A good research question is one that requires impartial responses and can be answered via existing sources of information. Also, a good research question seeks answers that actively contribute to a body of knowledge; hence, it is a question that is yet to be answered in your specific research context.

  • Open-Ended Questions

 An open-ended question is a type of research question that does not restrict respondents to a set of premeditated answer options. In other words, it is a question that allows the respondent to freely express his or her perceptions and feelings towards the research subject. 

Examples of Open-ended Questions

  • How do you deal with stress in the workplace?
  • What is a typical day at work like for you?
  • Close-ended Questions

A close-ended question is a type of survey question that restricts respondents to a set of predetermined answers such as multiple-choice questions . Close-ended questions typically require yes or no answers and are commonly used in quantitative research to gather numerical data from research participants. 

Examples of Close-ended Questions

  • Did you enjoy this event?
  • How likely are you to recommend our services?
  • Very Likely
  • Somewhat Likely
  • Likert Scale Questions

A Likert scale question is a type of close-ended question that is structured as a 3-point, 5-point, or 7-point psychometric scale . This type of question is used to measure the survey respondent’s disposition towards multiple variables and it can be unipolar or bipolar in nature. 

Example of Likert Scale Questions

  • How satisfied are you with our service delivery?
  • Very dissatisfied
  • Not satisfied
  • Very satisfied
  • Rating Scale Questions

A rating scale question is a type of close-ended question that seeks to associate a specific qualitative measure (rating) with the different variables in research. It is commonly used in customer experience surveys, market research surveys, employee reviews, and product evaluations. 

Example of Rating Questions

  • How would you rate our service delivery?

  Examples of a Bad Research Question

Knowing what bad research questions are would help you avoid them in the course of your systematic investigation. These types of questions are usually unfocused and often result in research biases that can negatively impact the outcomes of your systematic investigation. 

  • Loaded Questions

A loaded question is a question that subtly presupposes one or more unverified assumptions about the research subject or participant. This type of question typically boxes the respondent in a corner because it suggests implicit and explicit biases that prevent objective responses. 

Example of Loaded Questions

  • Have you stopped smoking?
  • Where did you hide the money?
  • Negative Questions

A negative question is a type of question that is structured with an implicit or explicit negator. Negative questions can be misleading because they upturn the typical yes/no response order by requiring a negative answer for affirmation and an affirmative answer for negation. 

Examples of Negative Questions

  • Would you mind dropping by my office later today?
  • Didn’t you visit last week?
  • Leading Questions  

A l eading question is a type of survey question that nudges the respondent towards an already-determined answer. It is highly suggestive in nature and typically consists of biases and unverified assumptions that point toward its premeditated responses. 

Examples of Leading Questions

  • If you enjoyed this service, would you be willing to try out our other packages?
  • Our product met your needs, didn’t it?

Research Questions

Definition:

Research questions are the specific questions that guide a research study or inquiry. These questions help to define the scope of the research and provide a clear focus for the study. Research questions are usually developed at the beginning of a research project and are designed to address a particular research problem or objective.

Types of Research Questions

Types of Research Questions are as follows:

Descriptive Research Questions

These aim to describe a particular phenomenon, group, or situation. For example:

  • What are the characteristics of the target population?
  • What is the prevalence of a particular disease in a specific region?

Exploratory Research Questions

These aim to explore a new area of research or generate new ideas or hypotheses. For example:

  • What are the potential causes of a particular phenomenon?
  • What are the possible outcomes of a specific intervention?

Explanatory Research Questions

These aim to understand the relationship between two or more variables or to explain why a particular phenomenon occurs. For example:

  • What is the effect of a specific drug on the symptoms of a particular disease?
  • What are the factors that contribute to employee turnover in a particular industry?

Predictive Research Questions

These aim to predict a future outcome or trend based on existing data or trends. For example :

  • What will be the future demand for a particular product or service?

  • Relevant : The research question should be relevant to the study and should address a current issue or problem in the field of research.
  • Testable : The research question should be testable through empirical evidence. It should be possible to collect data to answer the research question.
  • Concise : The research question should be concise and focused. It should not be too broad or too narrow.
  • Feasible : The research question should be feasible to answer within the constraints of the research design, time frame, and available resources.
  • Original : The research question should be original and should contribute to the existing knowledge in the field of research.
  • Significant : The research question should have significance and importance to the field of research. It should have the potential to provide new insights and knowledge to the field.
  • Ethical : The research question should be ethical and should not cause harm to any individuals or groups involved in the study.

Purpose of Research Questions

Research questions are the foundation of any research study as they guide the research process and provide a clear direction to the researcher. The purpose of research questions is to identify the scope and boundaries of the study, and to establish the goals and objectives of the research.

The main purpose of research questions is to help the researcher to focus on the specific area or problem that needs to be investigated. They enable the researcher to develop a research design, select the appropriate methods and tools for data collection and analysis, and to organize the results in a meaningful way.

Research questions also help to establish the relevance and significance of the study. They define the research problem, and determine the research methodology that will be used to address the problem. Research questions also help to determine the type of data that will be collected, and how it will be analyzed and interpreted.

Finally, research questions provide a framework for evaluating the results of the research. They help to establish the validity and reliability of the data, and provide a basis for drawing conclusions and making recommendations based on the findings of the study.

Advantages of Research Questions

There are several advantages of research questions in the research process, including:

  • Focus : Research questions help to focus the research by providing a clear direction for the study. They define the specific area of investigation and provide a framework for the research design.
  • Clarity : Research questions help to clarify the purpose and objectives of the study, which can make it easier for the researcher to communicate the research aims to others.
  • Relevance : Research questions help to ensure that the study is relevant and meaningful. By asking relevant and important questions, the researcher can ensure that the study will contribute to the existing body of knowledge and address important issues.
  • Consistency : Research questions help to ensure consistency in the research process by providing a framework for the development of the research design, data collection, and analysis.
  • Measurability : Research questions help to ensure that the study is measurable by defining the specific variables and outcomes that will be measured.
  • Replication : Research questions help to ensure that the study can be replicated by providing a clear and detailed description of the research aims, methods, and outcomes. This makes it easier for other researchers to replicate the study and verify the results.

Limitations of Research Questions

Limitations of Research Questions are as follows:

  • Subjectivity : Research questions are often subjective and can be influenced by personal biases and perspectives of the researcher. This can lead to a limited understanding of the research problem and may affect the validity and reliability of the study.
  • Inadequate scope : Research questions that are too narrow in scope may limit the breadth of the study, while questions that are too broad may make it difficult to focus on specific research objectives.
  • Unanswerable questions : Some research questions may not be answerable due to the lack of available data or limitations in research methods. In such cases, the research question may need to be rephrased or modified to make it more answerable.
  • Lack of clarity : Research questions that are poorly worded or ambiguous can lead to confusion and misinterpretation. This can result in incomplete or inaccurate data, which may compromise the validity of the study.
  • Difficulty in measuring variables : Some research questions may involve variables that are difficult to measure or quantify, making it challenging to draw meaningful conclusions from the data.
  • Lack of generalizability: Research questions that are too specific or limited in scope may not be generalizable to other contexts or populations. This can limit the applicability of the study’s findings and restrict its broader implications.

How To Write a Research Question

Deeptanshu D

Academic writing and research require a distinct focus and direction. A well-designed research question gives purpose and clarity to your research. In addition, it helps your readers understand the issue you are trying to address and explore.

Every time you want to know more about a subject, you will pose a question. The same idea is used in research as well. You must pose a question in order to effectively address a research problem. That's why the research question is an integral part of the research process. Additionally, it offers the author writing and reading guidelines, be it qualitative research or quantitative research.

In your research paper , you must single out just one issue or problem. The specific issue or claim you wish to address should be included in your thesis statement in order to clarify your main argument.

A good research question must have the following characteristics.

explain research questions

  • Should include only one problem in the research question
  • Should be able to find the answer using primary data and secondary data sources
  • Should be possible to resolve within the given time and other constraints
  • Detailed and in-depth results should be achievable
  • Should be relevant and realistic.
  • It should relate to your chosen area of research

While a larger project, like a thesis, might have several research questions to address, each one should be directed at your main area of study. Of course, you can use different research designs and research methods (qualitative research or quantitative research) to address various research questions. However, they must all be pertinent to the study's objectives.

What is a Research Question?

what-is-a-research-question

A research question is an inquiry that the research attempts to answer. It is the heart of the systematic investigation. Research questions are the most important step in any research project. In essence, it initiates the research project and establishes the pace for the specific research A research question is:

  • Clear : It provides enough detail that the audience understands its purpose without any additional explanation.
  • Focused : It is so specific that it can be addressed within the time constraints of the writing task.
  • Succinct: It is written in the shortest possible words.
  • Complex : It is not possible to answer it with a "yes" or "no", but requires analysis and synthesis of ideas before somebody can create a solution.
  • Argumental : Its potential answers are open for debate rather than accepted facts.

A good research question usually focuses on the research and determines the research design, methodology, and hypothesis. It guides all phases of inquiry, data collection, analysis, and reporting. You should gather valuable information by asking the right questions.

Why are Research Questions so important?

Regardless of whether it is a qualitative research or quantitative research project, research questions provide writers and their audience with a way to navigate the writing and research process. Writers can avoid "all-about" papers by asking straightforward and specific research questions that help them focus on their research and support a specific thesis.

Types of Research Questions

types-of-research-question

There are two types of research: Qualitative research and Quantitative research . There must be research questions for every type of research. Your research question will be based on the type of research you want to conduct and the type of data collection.

The first step in designing research involves identifying a gap and creating a focused research question.

Below is a list of common research questions that can be used in a dissertation. Keep in mind that these are merely illustrations of typical research questions used in dissertation projects. The real research questions themselves might be more difficult.

Example Research Questions

examples-of-research-question

The following are a few examples of research questions and research problems to help you understand how research questions can be created for a particular research problem.

Steps to Write Research Questions

steps-to-write-a-research-question

You can focus on the issue or research gaps you're attempting to solve by using the research questions as a direction.

If you're unsure how to go about writing a good research question, these are the steps to follow in the process:

  • Select an interesting topic Always choose a topic that interests you. Because if your curiosity isn’t aroused by a subject, you’ll have a hard time conducting research around it. Alos, it’s better that you pick something that’s neither too narrow or too broad.
  • Do preliminary research on the topic Search for relevant literature to gauge what problems have already been tackled by scholars. You can do that conveniently through repositories like Scispace , where you’ll find millions of papers in one place. Once you do find the papers you’re looking for, try our reading assistant, SciSpace Copilot to get simple explanations for the paper . You’ll be able to quickly understand the abstract, find the key takeaways, and the main arguments presented in the paper. This will give you a more contextual understanding of your subject and you’ll have an easier time identifying knowledge gaps in your discipline.

     Also: ChatPDF vs. SciSpace Copilot: Unveiling the best tool for your research

  • Consider your audience It is essential to understand your audience to develop focused research questions for essays or dissertations. When narrowing down your topic, you can identify aspects that might interest your audience.
  • Ask questions Asking questions will give you a deeper understanding of the topic. Evaluate your question through the What, Why, When, How, and other open-ended questions assessment.
  • Assess your question Once you have created a research question, assess its effectiveness to determine if it is useful for the purpose. Refine and revise the dissertation research question multiple times.

Additionally, use this list of questions as a guide when formulating your research question.

Are you able to answer a specific research question? After identifying a gap in research, it would be helpful to formulate the research question. And this will allow the research to solve a part of the problem. Is your research question clear and centered on the main topic? It is important that your research question should be specific and related to your central goal. Are you tackling a difficult research question? It is not possible to answer the research question with a simple yes or no. The problem requires in-depth analysis. It is often started with "How" and "Why."

Start your research Once you have completed your dissertation research questions, it is time to review the literature on similar topics to discover different perspectives.

Strong  Research Question Samples

Uncertain: How should social networking sites work on the hatred that flows through their platform?

Certain: What should social media sites like Twitter or Facebook do to address the harm they are causing?

This unclear question does not specify the social networking sites that are being used or what harm they might be causing. In addition, this question assumes that the "harm" has been proven and/or accepted. This version is more specific and identifies the sites (Twitter, Facebook), the type and extent of harm (privacy concerns), and who might be suffering from that harm (users). Effective research questions should not be ambiguous or interpreted.

Unfocused: What are the effects of global warming on the environment?

Focused: What are the most important effects of glacial melting in Antarctica on penguins' lives?

This broad research question cannot be addressed in a book, let alone a college-level paper. Focused research targets a specific effect of global heating (glacial  melting), an area (Antarctica), or a specific animal (penguins). The writer must also decide which effect will have the greatest impact on the animals affected. If in doubt, narrow down your research question to the most specific possible.

Too Simple: What are the U.S. doctors doing to treat diabetes?

Appropriately complex: Which factors, if any, are most likely to predict a person's risk of developing diabetes?

This simple version can be found online. It is easy to answer with a few facts. The second, more complicated version of this question is divided into two parts. It is thought-provoking and requires extensive investigation as well as evaluation by the author. So, ensure that a quick Google search should not answer your research question.

How to write a strong Research Question?

how-to-write-a-strong-research-question

The foundation of all research is the research question. You should therefore spend as much time as necessary to refine your research question based on various data.

You can conduct your research more efficiently and analyze your results better if you have great research questions for your dissertation, research paper , or essay .

The following criteria can help you evaluate the strength and importance of your research question and can be used to determine the strength of your research question:

  • Researchable
  • It should only cover one issue.
  • A subjective judgment should not be included in the question.
  • It can be answered with data analysis and research.
  • Specific and Practical
  • It should not contain a plan of action, policy, or solution.
  • It should be clearly defined
  • Within research limits
  • Complex and Arguable
  • It shouldn't be difficult to answer.
  • To find the truth, you need in-depth knowledge
  • Allows for discussion and deliberation
  • Original and Relevant
  • It should be in your area of study
  • Its results should be measurable
  • It should be original

Conclusion - How to write Research Questions?

Research questions provide a clear guideline for research. One research question may be part of a larger project, such as a dissertation. However, each question should only focus on one topic.

Research questions must be answerable, practical, specific, and applicable to your field. The research type that you use to base your research questions on will determine the research topic. You can start by selecting an interesting topic and doing preliminary research. Then, you can begin asking questions, evaluating your questions, and start your research.

What is a research question?

A research question is an essential tool to help guide your research paper, project, or thesis. It poses a specific question that you are seeking to answer in your paper. Research questions can be broad or narrow, and can change throughout the research process.

A good research question should be:

  • Focused on a single issue
  • Specific enough to answer thoroughly in your paper
  • Feasible to answer within the length of your paper
  • Researchable using the resources available to you
  • Relevant to your field of study and/or to society at large

The length of your paper and the research you're able to locate will help to shape your research question. A longer paper, like a thesis or dissertation, may require multiple research questions.

The answer to your research question develops into your thesis statement .

Writing Your Research Question

Chose a Topic

You should choose a research topic that is interesting to you. This will make the research and writing process much more bearable.

A good way to begin brainstorming research questions is to list all the questions you would like to see answered, or topics you would like to learn more about. You may have been provided a list of potential topics by your professor, if none are interesting to you ask if you can develop your own.

It is better to start broad and narrow down your focus as you go.

Do Preliminary Research

Reference materials like encyclopedias can also be good for this purpose.

Narrow Your Topic

Now that you have a basic idea of what research exists on your topic, you can begin to narrow your focus.

Make sure that your question is specific enough that it can be answered thoroughly in the length of your paper.

' src=

Cecilia is living through a tough situation in her research life. Figuring out where to begin, how to start her research study, and how to pose the right question for her research quest, is driving her insane. Well, questions, if not asked correctly, have a tendency to spiral us!

Image Source: https://phdcomics.com/

Questions lead everyone to answers. Research is a quest to find answers. Not the vague questions that Cecilia means to answer, but definitely more focused questions that define your research. Therefore, asking appropriate question becomes an important matter of discussion.

A well begun research process requires a strong research question. It directs the research investigation and provides a clear goal to focus on. Understanding the characteristics of comprising a good research question will generate new ideas and help you discover new methods in research.

In this article, we are aiming to help researchers understand what is a research question and how to write one with examples.

Table of Contents

What Is a Research Question?

A good research question defines your study and helps you seek an answer to your research. Moreover, a clear research question guides the research paper or thesis to define exactly what you want to find out, giving your work its objective. Learning to write a research question is the beginning to any thesis, dissertation , or research paper. Furthermore, the question addresses issues or problems which is answered through analysis and interpretation of data.

Why Is a Research Question Important?

A strong research question guides the design of a study. Moreover, it helps determine the type of research and identify specific objectives. Research questions state the specific issue you are addressing and focus on outcomes of the research for individuals to learn. Therefore, it helps break up the study into easy steps to complete the objectives and answer the initial question.

Types of Research Questions

Research questions can be categorized into different types, depending on the type of research you want to undergo. Furthermore, knowing the type of research will help a researcher determine the best type of research question to use.

1. Qualitative Research Question

Qualitative questions concern broad areas or more specific areas of research. However, unlike quantitative questions, qualitative research questions are adaptable, non-directional and more flexible. Qualitative research question focus on discovering, explaining, elucidating, and exploring.

i. Exploratory Questions

This form of question looks to understand something without influencing the results. The objective of exploratory questions is to learn more about a topic without attributing bias or preconceived notions to it.

Research Question Example: Asking how a chemical is used or perceptions around a certain topic.

ii. Predictive Questions

Predictive research questions are defined as survey questions that automatically predict the best possible response options based on text of the question. Moreover, these questions seek to understand the intent or future outcome surrounding a topic.

Research Question Example: Asking why a consumer behaves in a certain way or chooses a certain option over other.

iii. Interpretive Questions

This type of research question allows the study of people in the natural setting. The questions help understand how a group makes sense of shared experiences with regards to various phenomena. These studies gather feedback on a group’s behavior without affecting the outcome.

Research Question Example: How do you feel about AI assisting publishing process in your research?

2. Quantitative Research Question

Quantitative questions prove or disprove a researcher’s hypothesis through descriptions, comparisons, and relationships. These questions are beneficial when choosing a research topic or when posing follow-up questions that garner more information.

i. Descriptive Questions

It is the most basic type of quantitative research question and it seeks to explain when, where, why, or how something occurred. Moreover, they use data and statistics to describe an event or phenomenon.

Research Question Example: How many generations of genes influence a future generation?

ii. Comparative Questions

Sometimes it’s beneficial to compare one occurrence with another. Therefore, comparative questions are helpful when studying groups with dependent variables.

Example: Do men and women have comparable metabolisms?

iii. Relationship-Based Questions

This type of research question answers influence of one variable on another. Therefore, experimental studies use this type of research questions are majorly.

Example: How is drought condition affect a region’s probability for wildfires.  

How to Write a Good Research Question?

good research question

1. Select a Topic

The first step towards writing a good research question is to choose a broad topic of research. You could choose a research topic that interests you, because the complete research will progress further from the research question. Therefore, make sure to choose a topic that you are passionate about, to make your research study more enjoyable.

2. Conduct Preliminary Research

After finalizing the topic, read and know about what research studies are conducted in the field so far. Furthermore, this will help you find articles that talk about the topics that are yet to be explored. You could explore the topics that the earlier research has not studied.

3. Consider Your Audience

The most important aspect of writing a good research question is to find out if there is audience interested to know the answer to the question you are proposing. Moreover, determining your audience will assist you in refining your research question, and focus on aspects that relate to defined groups.

4. Generate Potential Questions

The best way to generate potential questions is to ask open ended questions. Questioning broader topics will allow you to narrow down to specific questions. Identifying the gaps in literature could also give you topics to write the research question. Moreover, you could also challenge the existing assumptions or use personal experiences to redefine issues in research.

5. Review Your Questions

Once you have listed few of your questions, evaluate them to find out if they are effective research questions. Moreover while reviewing, go through the finer details of the question and its probable outcome, and find out if the question meets the research question criteria.

6. Construct Your Research Question

There are two frameworks to construct your research question. The first one being PICOT framework , which stands for:

  • Population or problem
  • Intervention or indicator being studied
  • Comparison group
  • Outcome of interest
  • Time frame of the study.

The second framework is PEO , which stands for:

  • Population being studied
  • Exposure to preexisting conditions
  • Outcome of interest.

Research Question Examples

  • How might the discovery of a genetic basis for alcoholism impact triage processes in medical facilities?
  • How do ecological systems respond to chronic anthropological disturbance?
  • What are demographic consequences of ecological interactions?
  • What roles do fungi play in wildfire recovery?
  • How do feedbacks reinforce patterns of genetic divergence on the landscape?
  • What educational strategies help encourage safe driving in young adults?
  • What makes a grocery store easy for shoppers to navigate?
  • What genetic factors predict if someone will develop hypothyroidism?
  • Does contemporary evolution along the gradients of global change alter ecosystems function?

How to Write a Good Research Question (w/ Examples)

explain research questions

What is a Research Question?

A research question is the main question that your study sought or is seeking to answer. A clear research question guides your research paper or thesis and states exactly what you want to find out, giving your work a focus and objective. Learning  how to write a hypothesis or research question is the start to composing any thesis, dissertation, or research paper. It is also one of the most important sections of a research proposal . 

A good research question not only clarifies the writing in your study; it provides your readers with a clear focus and facilitates their understanding of your research topic, as well as outlining your study’s objectives. Before drafting the paper and receiving research paper editing (and usually before performing your study), you should write a concise statement of what this study intends to accomplish or reveal.

Research Question Writing Tips

Listed below are the important characteristics of a good research question:

A good research question should:

  • Be clear and provide specific information so readers can easily understand the purpose.
  • Be focused in its scope and narrow enough to be addressed in the space allowed by your paper
  • Be relevant and concise and express your main ideas in as few words as possible, like a hypothesis.
  • Be precise and complex enough that it does not simply answer a closed “yes or no” question, but requires an analysis of arguments and literature prior to its being considered acceptable. 
  • Be arguable or testable so that answers to the research question are open to scrutiny and specific questions and counterarguments.

Some of these characteristics might be difficult to understand in the form of a list. Let’s go into more detail about what a research question must do and look at some examples of research questions.

The research question should be specific and focused 

Research questions that are too broad are not suitable to be addressed in a single study. One reason for this can be if there are many factors or variables to consider. In addition, a sample data set that is too large or an experimental timeline that is too long may suggest that the research question is not focused enough.

A specific research question means that the collective data and observations come together to either confirm or deny the chosen hypothesis in a clear manner. If a research question is too vague, then the data might end up creating an alternate research problem or hypothesis that you haven’t addressed in your Introduction section .

The research question should be based on the literature 

An effective research question should be answerable and verifiable based on prior research because an effective scientific study must be placed in the context of a wider academic consensus. This means that conspiracy or fringe theories are not good research paper topics.

Instead, a good research question must extend, examine, and verify the context of your research field. It should fit naturally within the literature and be searchable by other research authors.

References to the literature can be in different citation styles and must be properly formatted according to the guidelines set forth by the publishing journal, university, or academic institution. This includes in-text citations as well as the Reference section . 

The research question should be realistic in time, scope, and budget

There are two main constraints to the research process: timeframe and budget.

A proper research question will include study or experimental procedures that can be executed within a feasible time frame, typically by a graduate doctoral or master’s student or lab technician. Research that requires future technology, expensive resources, or follow-up procedures is problematic.

A researcher’s budget is also a major constraint to performing timely research. Research at many large universities or institutions is publicly funded and is thus accountable to funding restrictions. 

The research question should be in-depth

Research papers, dissertations and theses , and academic journal articles are usually dozens if not hundreds of pages in length.

A good research question or thesis statement must be sufficiently complex to warrant such a length, as it must stand up to the scrutiny of peer review and be reproducible by other scientists and researchers.

Research Question Types

Qualitative and quantitative research are the two major types of research, and it is essential to develop research questions for each type of study. 

Quantitative Research Questions

Quantitative research questions are specific. A typical research question involves the population to be studied, dependent and independent variables, and the research design.

In addition, quantitative research questions connect the research question and the research design. In addition, it is not possible to answer these questions definitively with a “yes” or “no” response. For example, scientific fields such as biology, physics, and chemistry often deal with “states,” in which different quantities, amounts, or velocities drastically alter the relevance of the research.

As a consequence, quantitative research questions do not contain qualitative, categorical, or ordinal qualifiers such as “is,” “are,” “does,” or “does not.”

Categories of quantitative research questions

Qualitative research questions.

In quantitative research, research questions have the potential to relate to broad research areas as well as more specific areas of study. Qualitative research questions are less directional, more flexible, and adaptable compared with their quantitative counterparts. Thus, studies based on these questions tend to focus on “discovering,” “explaining,” “elucidating,” and “exploring.”

Categories of qualitative research questions

Quantitative and qualitative research question examples.

Good and Bad Research Question Examples

Below are some good (and not-so-good) examples of research questions that researchers can use to guide them in crafting their own research questions.

Research Question Example 1

The first research question is too vague in both its independent and dependent variables. There is no specific information on what “exposure” means. Does this refer to comments, likes, engagement, or just how much time is spent on the social media platform?

Second, there is no useful information on what exactly “affected” means. Does the subject’s behavior change in some measurable way? Or does this term refer to another factor such as the user’s emotions?

Research Question Example 2

In this research question, the first example is too simple and not sufficiently complex, making it difficult to assess whether the study answered the question. The author could really only answer this question with a simple “yes” or “no.” Further, the presence of data would not help answer this question more deeply, which is a sure sign of a poorly constructed research topic.

The second research question is specific, complex, and empirically verifiable. One can measure program effectiveness based on metrics such as attendance or grades. Further, “bullying” is made into an empirical, quantitative measurement in the form of recorded disciplinary actions.

Steps for Writing a Research Question

Good research questions are relevant, focused, and meaningful. It can be difficult to come up with a good research question, but there are a few steps you can follow to make it a bit easier.

1. Start with an interesting and relevant topic

Choose a research topic that is interesting but also relevant and aligned with your own country’s culture or your university’s capabilities. Popular academic topics include healthcare and medical-related research. However, if you are attending an engineering school or humanities program, you should obviously choose a research question that pertains to your specific study and major.

Below is an embedded graph of the most popular research fields of study based on publication output according to region. As you can see, healthcare and the basic sciences receive the most funding and earn the highest number of publications.

2. Do preliminary research  

You can begin doing preliminary research once you have chosen a research topic. Two objectives should be accomplished during this first phase of research. First, you should undertake a preliminary review of related literature to discover issues that scholars and peers are currently discussing. With this method, you show that you are informed about the latest developments in the field.

Secondly, identify knowledge gaps or limitations in your topic by conducting a preliminary literature review . It is possible to later use these gaps to focus your research question after a certain amount of fine-tuning.

3. Narrow your research to determine specific research questions

You can focus on a more specific area of study once you have a good handle on the topic you want to explore. Focusing on recent literature or knowledge gaps is one good option. 

By identifying study limitations in the literature and overlooked areas of study, an author can carve out a good research question. The same is true for choosing research questions that extend or complement existing literature.

4. Evaluate your research question

Make sure you evaluate the research question by asking the following questions:

Is my research question clear?

The resulting data and observations that your study produces should be clear. For quantitative studies, data must be empirical and measurable. For qualitative, the observations should be clearly delineable across categories.

Is my research question focused and specific?

A strong research question should be specific enough that your methodology or testing procedure produces an objective result, not one left to subjective interpretation. Open-ended research questions or those relating to general topics can create ambiguous connections between the results and the aims of the study. 

Is my research question sufficiently complex?

The result of your research should be consequential and substantial (and fall sufficiently within the context of your field) to warrant an academic study. Simply reinforcing or supporting a scientific consensus is superfluous and will likely not be well received by most journal editors.

Editing Your Research Question

Your research question should be fully formulated well before you begin drafting your research paper. However, you can receive English paper editing and proofreading services at any point in the drafting process. Language editors with expertise in your academic field can assist you with the content and language in your Introduction section or other manuscript sections. And if you need further assistance or information regarding paper compositions, in the meantime, check out our academic resources , which provide dozens of articles and videos on a variety of academic writing and publication topics.

A research question is the main query that researchers seek to answer in their study. It serves as the basis for a scholarly project such as research paper, thesis or dissertation. A good research question should be clear, relevant and specific enough to guide the research process. It should also be open-ended, meaning that it allows for multiple possible answers or interpretations.

If you have located your general subject and main sources but still aren’t quite sure about the exact research questions for your paper, this guide will help you out. First, we will explore the concept of it together, so you could answer it in your work. Then some simple steps on composing your inquiry will be suggested. In the end, we will draw your attention to some specific details which can make your work good or bad. Sometimes it’s just easier to delegate all challenging tasks to a reliable research paper service . StudyCrumb is a trustable network of qualified writers ready to efficiently solve students’ challenges.

What Is a Good Research Question: Full Definition

Good research questions provide a concise definition of a problem. As a scholar, your main goal at the beginning is to select the main focus. It should be narrow enough so you could examine it within your deadline. Your work should be focused on something specific. Otherwise, it will require too much work and might not produce clear answers. At the same time your answer should be arguable and supported by data you’ve collected. Take a look at this example:

example of a good research question

How to Write a Research Question: Step-By-Step Guide

In this section we will examine the process of developing a research question. We will guide you through it, step by step. Keep in mind that your subject should be important for your audience. So it requires some preliminary study and brainstorming. Let’s take a closer look at the main steps.

Step 1. Choose a Broad Topic for Your Research Paper Question

First, you need to decide on your general direction. When trying to identify your research paper questions, it is better to choose an area you are really interested in. You should be able to obtain enough data to write something about this topic. Therefore, do not choose something out of your reach. At the same time, your broad topic should not be too simple. Research paper questions that can be answered without any study would hardly make any sense for your project.

Step 2. Do Preliminary Reading Before Starting Your Research Question

Next, it is time we explore the context of the selected topic. You wouldn’t want to choose research questions that have already been examined and answered in detail. On the other hand, choosing a topic that is a complete ‘terra incognita’ might be a bridge too far for your project. Browse through available sources that are related to this topic. You should try and find out what has been discovered about it before. Do you see a gap that you can fill with your study? You can proceed with developing your exact inquiry! Have no time for in-depth topic exploration? Leave this task to professionals. Entrust your “ write my research paper ” order to StudyCrumb and get a top-notch work.

Step 3. Consider an Audience for Your Research Question

It is good to know your reader well to be able to convey your ideas and results to them in the best possible way. Before writing research questions for your projects, you might need to perform a brief analysis of your audience. That's how you'll be able to understand what is interesting for them and what is not. This will allow you to make better decisions when narrowing your broad topic down. Select a topic that is interesting for your reader! This would contribute much to the success for writing a research paper .

Step 4. Start Asking a Good Research Question

After you have considered your options, go ahead and compose the primary subject of your paper. What makes a good research question? It should highlight some problematic and relevant aspects of the general topic. So, after it is answered, you should have obtained some new valuable knowledge about the subject.  Typically scholars start narrowing down their general topic by asking ‘how’, ‘why’ or ‘what’s next’ questions. This approach might help you come up with a great idea quickly.

Step 5. Evaluate Your Research Question

Finally, after you have composed a research paper question, you should take a second look at it and see if it is good enough for your paper. It would be useful to analyze it from the following sides:

  • Is it clear for your audience?
  • Is it complex enough to require significant study?
  • Is it focused on a certain aspect of your general topic?

You might use the help of your peers or your friends at this step. You can also show it to your tutor and ask for their opinion.

Types of Research Questions: Which to Choose

A number of research questions types are available for use in a paper. They are divided into two main groups:

Qualitative questions:

  • Explanatory
  • Ethnographic

Quantitative questions:

  • Descriptive
  • Comparative
  • Relationship based.

Selecting a certain type would impact the course of your study. We suggest you think about it carefully. Below you can find a few words about each type. Also, you can seek proficient help from academic experts. Buy a research paper from real pros and forget about stress once and for all.

Qualitative Research Questions: Definition With Example

When doing qualitative research, you are expected to aim to understand the different aspects and qualities of your target problem. Therefore, your thesis should focus on analyzing people’s experience, ideas and reflections rather than on obtaining some statistical data and calculating trends. Thus, this inquiry typically requires observing people’s behavior, interacting with them and learning how they interpret your target problem.  Let’s illustrate this with an example:

Example of Qualitative Research Questions

What Is Contextual Research Questions

Contextual research revolves around examining your subject in its natural, everyday environment. It may be watching animals living in their usual habitats or people doing their normal activities in their familiar surroundings (at home, at school or at office). This academic approach helps to understand the role of the context. You'll be able to better explain connections between your problem, its environment and outcomes. This type of inquiry ought to be narrow enough. You shouldn’t have to examine each and every aspect of the selected problem in your paper. Consider this example:

Example of Contextual Research Questions

Definition and Sample of Evaluative Research Questions

Evaluative research is performed in order to carefully assess the qualities of a selected object, individual, group, system or concept. It typically serves the purpose of collecting evidence that supports or contradicts solutions for a problem. This type of inquiry should focus on how useful a certain quality is for solving the problem.  To conduct such study, you need to examine selected qualities in detail. Then, you should assume whether they match necessary criteria. It might include some quantitative methods such as collecting statistics. Although, the most important part is analyzing the qualities. If you need some examples, here’s one for you:

Sample of Evaluative Research Questions

Explanatory Research Questions: Definition With Example

Your paper can be dedicated to explaining a certain phenomenon, finding its reasons and important relationships between it and other important things. Your explanatory research question should aim to highlight issues, uncertainties and problematic aspects of your subject. So, your study should bring clarity about these qualities. It should show how and why they have developed this way. An explanation may include showing causes and effects of issues in question, comparing the selected phenomenon to other similar types and showing whether the selected qualities match some predefined criteria. If you need some examples, check this one:

Example of Explanatory Research Questions

Generative Research Questions

This type of research is conducted in order to better understand the subject. With its help, you can find some new solutions or opportunities for improvement. Therefore, its main purpose is to develop a theoretical basis for further actions. You need to compose your generative research questions in a way that facilitates obtaining new ideas. It would help to begin with asking ‘why’, ‘what is the relationship between the subject and the problems X, Y, and Z’, ‘what can be improved here’, ‘how we can prevent it’ and so on. Need relevant examples? We’ve got one for you:

Example of Generative Research Questions

Ethnographic Research Question

Ethnography research is focused on a particular group of people. The aim is to study their behavior, typical reactions to certain events or information, needs, preferences or habits. Important parameters of this group which are most relevant to your general subject are taken into consideration. These are age, sex, language, religion, ethnicity, social status and so on. Main method in this case is first-hand observation of people from the selected group during an extended period of time. If you need strong examples, here’s one:

Ethnographic Research Question Example

Quantitative Research Questions: Full Definition With Examples

Quantitative research deals with data – first of all, it is numeric data. It involves mathematical calculations and statistical analysis. It helps to obtain knowledge which is mostly expressed in numbers, graphs and tables. Unlike the qualitative type, the purpose of quantitative research is finding patterns, calculating probabilities, testing causal relationships and making predictions. It is focused on testing theories and hypotheses. (We have the whole blog on what is a hypothesis .) It is mostly used in natural and social sciences. These are: chemistry, biology, psychology, economics, sociology, marketing, etc. Here are a couple of examples:

Quantitative Research Questions Example

Descriptive Research Questions: Definition With Example

This is probably the most widespread type of quantitative research question. Such inquiries seek to explain when, where, why, or how something occurred. They describe it accurately and systematically. These inquiries typically start with ‘what’. You are expected to use various methods to investigate one or more variables and determine their dependencies. Note, however, that you cannot control or manipulate any of these variables. You can only observe and measure them. Looking for some interesting examples? Here is one:

Descriptive Research Questions

Definition of Comparative Research Questions

Comparative research question is used to highlight different variables and provide numerical evidence. This type is based on comparing one object, parameter or issue with another one of a similar kind. It can help to discover the differences between two or more groups by examining their outcome variables.  Take a look at these two examples:

Example of Comparative Research Questions

Relationship Research Questions

We conduct this type of research when we need to make it clear whether one parameter of a selected object causes another one. A relationship based quantitative research question should help us to explore and define trends and interactions between two or more variables. Are these two things mutually dependent? What kind of dependence is it? How has it developed? And what are possible outcomes of this connection? Here is an example of relationship-based quantitative research questions:

Examples of Good and Bad Research Questions

Everyone is interested in getting the best possible appraisal for their study. Choosing a topic which doesn't suit your specific situation may be discouraging. Thus, the quality of your paper might get affected by a poor choice. We have put together some good and bad examples so that you could avoid such mistakes.

Good Research Questions Examples

It is important to include clear terms into your questions. Otherwise, it would be difficult for you to plan your investigation properly. Also, they must be focused on a certain subject, not multiple ones. And finally, it should be possible to answer them. Let’s review several good examples:

Good Research Questions Example

Examples of Bad Research Questions

It is difficult to evaluate qualities of objects, individuals or groups if your purpose is not clear. This is why you shouldn’t create unclear research questions or try to focus on many problems at once. Some preliminary study might help to understand what you should focus on. Here are several bad examples:

6. Developing Your Research Question

Because of all their influence, you might worry that research questions are very difficult to develop. Sometimes it can seem that way. But we’ll help you get the hang of it and, luckily, none of us has to come up with perfect ones right off. It’s more like doing a rough draft and then improving it. That’s why we talk about developing research questions instead of just writing them.

Steps for Developing a Research Question

The steps for developing a research question, listed below, can help you organize your thoughts.

Step 1: Pick a topic (or consider the one assigned to you).

Step 2: Write a narrower/smaller topic that is related to the first.

Step 3: List some potential questions that could logically be asked in relation to the narrow topic.

Step 4: Pick the question that you are most interested in.

Step 5: Change the question you’re interested in so that it is more focused and specific.

MOVIE: Developing Research Questions

As you view this short video on how to develop research questions, think about the steps. Which step do you think is easiest? Which do you think is the hardest?  

Once you know the steps and their order, only three skills are involved in developing a research question:

  • Imagining narrower topics about a larger one,
  • Thinking of questions that stem from a narrow topic, and
  • Focusing questions to eliminate their vagueness.

Every time you use these skills, it’s important to evaluate what you have produced—that’s just part of the process of turning rough drafts into more finished products.

Start with a narrow topic, think of questions, and then focus those questions.

ACTIVITY:  Developing a Research Question

Maybe you have a topic in mind but aren’t sure how to form a research question around it. The trick is to think of a question related to your topic but not answerable with a quick search. Also, try to be specific so that your research question can be fully answered in the final product for your research assignment.

ACTIVITY: Thinking of Questions

For each of the narrow topics below, think of a research question that is logically related to that topic. (Remember that good research questions often, but not always, start with “Why” or “How” because questions that begin that way usually require more analysis.)

  • U.S. investors’ attitudes about sustainability
  • College students’ use of Snapchat
  • The character Scout in To Kill a Mockingbird
  • Nature-inspired nanotechnologies
  • Marital therapy

After you think of each research question, evaluate it by asking whether it is:

  • Logically related to the topic
  • In question form
  • Not answerable with a quick Google search
  • Specific, not vague

Sometimes the first draft of a research question is still too broad, which can make your search for sources more challenging. Refining your question to remove vagueness or to target a specific aspect of the topic can help.

ACTIVITY: Focusing Questions

The first draft research questions below are not focused enough. Read them and identify at least one area of vagueness in each. Check your vagueness with what we identified. It’s great if you found more than we did because that can lead to research questions of greater specificity. See the bottom of the page for our answers.

First Drafts of Research Questions:

  • Why have most electric car company start-ups failed?
  • How do crabapple trees develop buds?
  • How has NASA helped America?
  • Why do many first-time elections soon after a country overthrows a dictator result in very conservative elected leaders?
  • How is music composed and performed mostly by African-Americans connected to African-American history?

ANSWER TO ACTIVITY: Focusing Questions

Some answers to the “Focusing Questions” Activity above are:

Question 1: Why have most electric car company start-ups failed? Vagueness: Which companies are we talking about? Worldwide or in a particular country?

Question 2: How do crabapple trees develop buds? Vagueness: There are several kinds of crabapples. Should we talk only about one kind? Does it matter where the crabapple tree lives?

Question 3: How has NASA helped America? Vagueness: NASA has had many projects. Should we should focus on one project they completed? Or projects during a particular time period?

Question 4: Why do many first-time elections soon after a country overthrows a dictator result in very conservative elected leaders? Vagueness: What time period are we talking about? Many dictators have been overthrown and many countries have been involved. Perhaps we should focus on one country or one dictator or one time period.

Question 5: How is music composed and performed mostly by African-Americans connected to African-American history? Vagueness: What kinds of music? Any particular performers and composers? When?

Research questions explained plus examples

Research Questions - Toolshero

Research questions: This article provides a practical explanation of the topic of research questions . The article begins with a general definition of the term “research question” and an explanation of the different types of research questions. You will also find several useful tips for developing your own research question and sub-questions, for example, for a thesis or other research project. Enjoy reading!

What is a research question?

When conducting research, the research question and sub-questions are essential. The research question reflects the main question of the research, and the sub-questions contribute to answering this main question. Therefore, it is essential to carefully consider the formulation of the questions.

A good research question is concrete, relevant, and well-defined. It should be clear what is being researched and what the purpose of the research is. The sub-questions should match this and should be specific enough to be answered within the research. The sub-questions should also contribute to answering the main question.

Free Toolshero ebook

Example research question

An example of a research question with sub-questions could be: “How can communication between employees and managers be improved within organization X?” The sub-questions could be:

  • What does the current communication structure look like within organization X?
  • What are the obstacles to communication between employees and managers?
  • What communication tools are currently used, and are they effective?
  • What are the best practices for improving communication between employees and managers?

Creating good research questions and sub-questions is important for carrying out a clear and relevant study. By paying sufficient attention to this, the research can be carried out efficiently and effectively, and valuable results can be achieved.

Common types of research questions

Research questions types - Toolshero

Figure 1 – 4 types of Research questions

1. Descriptive research questions

These questions focus on describing a phenomenon, situation, or population. They are aimed at gathering information about what is going on and what is known about the research topic. An example of a descriptive research question is: “What percentage of students at university X have a part-time job alongside their studies?”

2. Explanatory research questions

These questions focus on finding explanations for a particular phenomenon or situation. They aim to find causal relationships between different variables. An example of an explanatory research question is: “What is the relationship between stress and sleep deprivation among healthcare workers?”

3. Predictive research questions

These questions focus on predicting future events or outcomes based on certain variables or factors. They aim to find patterns and trends that can help make predictions. An example of a predictive research question is: “How much is the sales of product X expected to increase in the coming year?”

4. Evaluative research questions

These questions focus on evaluating the effectiveness or efficiency of a particular intervention, policy, or program. They aim to assess the impact of a particular action or change. An example of an evaluative research question is: “What is the effect of introducing a new teaching method on the academic performance of students?”

It is important to choose the right type of research question that fits the purpose of the research and the research method used. By formulating a clear and specific research question, a researcher can work more effectively and achieve the desired results.

What criteria should a good research question meet?

Below you will find six criteria that a good research question should meet. These criteria are specificity, clarity, relevance, feasibility, significance, and interest.

The research question must be formulated clearly and specifically, so that it is clear what the subject of the research is.

The research question must be relevant to the field and build upon existing knowledge and insights.

The research question must be feasible within the available time, resources, and knowledge of the researcher.

The research question must be verifiable through empirical research or data analysis, so that the results can be objectively evaluated.

The research question must be original and contribute to expanding existing knowledge or developing new insights.

The research question must be challenging and inspiring, so that it motivates the researcher to work hard and perform at a high level.

How to write a good research question?

With the following steps, you can formulate a good research question that is relevant to the field in which you are conducting research.

Step 1: choose a topic

Choose a topic that is relevant to your field and contains keywords that people search for. Use a tool such as Google Keyword Planner to find keywords.

Step 2: prepare

Read literature and articles about the topic and identify gaps in knowledge or conflicting results that are worth further investigation.

Step 3: develop a preliminary research question

Formulate a general preliminary research question based on the findings from the literature. Make sure that this question is clear, concise, and relevant. Use relevant terms in your question.

Step 4: refine

Refine the general question into a specific question that can be answered through empirical research or data analysis. Use clear and simple language, and avoid jargon.

Step 5: check

Check if the question meets the characteristics of a good research question: is the question specific, relevant, feasible, verifiable, original, and inspiring?

Other tips for developing a research question for your thesis

Developing a good research question is essential for a successful thesis. Here are some tips that can help you develop a research question:

Choose a relevant topic

Choose a topic that is relevant to your field of study and that you are passionate about. This will increase your motivation and help you make a meaningful contribution to your field.

Determine the purpose of your research

Ask yourself what you want to achieve with your research. Do you want to discover a new problem, solve an existing problem, or introduce a new concept? Be specific Make sure that your research question is specific and not too broad. It should have a clear purpose and focus on a limited topic.

Use clear language

Make sure that your research question is clear and understandable to others. Avoid jargon and technical terms, unless they are necessary for the context of your research.

Writing Strong Research Questions | Criteria & Examples

Published on 30 October 2022 by Shona McCombes . Revised on 12 December 2023.

A research question pinpoints exactly what you want to find out in your work. A good research question is essential to guide your research paper , dissertation , or thesis .

All research questions should be:

  • Focused on a single problem or issue
  • Researchable using primary and/or secondary sources
  • Feasible to answer within the timeframe and practical constraints
  • Specific enough to answer thoroughly
  • Complex enough to develop the answer over the space of a paper or thesis
  • Relevant to your field of study and/or society more broadly

Writing Strong Research Questions

Table of contents

How to write a research question, what makes a strong research question, research questions quiz, frequently asked questions.

You can follow these steps to develop a strong research question:

  • Choose your topic
  • Do some preliminary reading about the current state of the field
  • Narrow your focus to a specific niche
  • Identify the research problem that you will address

The way you frame your question depends on what your research aims to achieve. The table below shows some examples of how you might formulate questions for different purposes.

Using your research problem to develop your research question

Note that while most research questions can be answered with various types of research , the way you frame your question should help determine your choices.

Prevent plagiarism, run a free check.

Research questions anchor your whole project, so it’s important to spend some time refining them. The criteria below can help you evaluate the strength of your research question.

Focused and researchable

Feasible and specific, complex and arguable, relevant and original.

The way you present your research problem in your introduction varies depending on the nature of your research paper . A research paper that presents a sustained argument will usually encapsulate this argument in a thesis statement .

A research paper designed to present the results of empirical research tends to present a research question that it seeks to answer. It may also include a hypothesis – a prediction that will be confirmed or disproved by your research.

As you cannot possibly read every source related to your topic, it’s important to evaluate sources to assess their relevance. Use preliminary evaluation to determine whether a source is worth examining in more depth.

This involves:

  • Reading abstracts , prefaces, introductions , and conclusions
  • Looking at the table of contents to determine the scope of the work
  • Consulting the index for key terms or the names of important scholars

An essay isn’t just a loose collection of facts and ideas. Instead, it should be centered on an overarching argument (summarised in your thesis statement ) that every part of the essay relates to.

The way you structure your essay is crucial to presenting your argument coherently. A well-structured essay helps your reader follow the logic of your ideas and understand your overall point.

A research hypothesis is your proposed answer to your research question. The research hypothesis usually includes an explanation (‘ x affects y because …’).

A statistical hypothesis, on the other hand, is a mathematical statement about a population parameter. Statistical hypotheses always come in pairs: the null and alternative hypotheses. In a well-designed study , the statistical hypotheses correspond logically to the research hypothesis.

Types of Research Questions

Research questions can be categorized into different types, depending on the type of research to be undertaken.

Qualitative questions concern broad areas or more specific areas of research and focus on discovering, explaining and exploring.  Types of qualitative questions include:

  • Exploratory Questions, which seeks to understand without influencing the results.  The objective is to learn more about a topic without bias or preconceived notions.
  • Predictive Questions, which seek to understand the intent or future outcome around a topic.
  • Interpretive Questions, which tries to understand people’s behavior in a natural setting.  The objective is to understand how a group makes sense of shared experiences with regards to various phenomena.

Quantitative questions prove or disprove a  researcher’s hypothesis and are constructed to express the relationship between variables  and whether this relationship is significant.  Types of quantitative questions include:

  • Descriptive questions , which are the most basic type of quantitative research question and seeks to explain the when, where, why or how something occurred. 
  • Comparative questions are helpful when studying groups with dependent variables where one variable is compared with another.
  • Relationship-based questions try to answer whether or not one variable has an influence on another.  These types of question are generally used in experimental research questions.

Research Question Frameworks

Research question frameworks have been designed to help structure research questions and clarify the main concepts. Not every question can fit perfectly into a framework, but using even just parts of a framework can help develop a well-defined research question. The framework to use depends on the type of question to be researched.   There are over 25 research question frameworks available.  The University of Maryland has a nice table listing out several of these research question frameworks, along with what the acronyms mean and what types of questions/disciplines that may be used for.

The process of developing a good research question involves taking your topic and breaking each aspect of it down into its component parts.

The "Well-Built Clinical Question“: PICO(T)

One well-established framework that can be used both for refining questions and developing strategies is known as PICO(T). The PICO framework was designed primarily for questions that include interventions and comparisons, however other types of questions may also be able to follow its principles.  If the PICO(T) framework does not precisely fit your question, using its principles (see alternative component suggestions) can help you to think about what you want to explore even if you do not end up with a true PICO question.

A PICO(T) question has the following components:

  • P : The patient’s disorder or disease or problem of interest / research object
  • I: The intervention, exposure or finding under review / Application of a theory or method
  • C: A comparison intervention or control (if applicable- not always present)/ Alternative theories or methods (or, in their absence, the null hypothesis)
  • O : The outcome(s) (desired or of interest) / Knowledge generation
  • T : (The time factor or period)

Keep in mind that solely using a tool will not enable you to design a good question. What is required is for you to think, carefully, about exactly what you want to study and precisely what you mean by each of the things that you think you want to study.

How to Define a Research Problem | Ideas & Examples

Published on November 2, 2022 by Shona McCombes and Tegan George. Revised on May 31, 2023.

A research problem is a specific issue or gap in existing knowledge that you aim to address in your research. You may choose to look for practical problems aimed at contributing to change, or theoretical problems aimed at expanding knowledge.

Some research will do both of these things, but usually the research problem focuses on one or the other. The type of research problem you choose depends on your broad topic of interest and the type of research you think will fit best.

This article helps you identify and refine a research problem. When writing your research proposal or introduction , formulate it as a problem statement and/or research questions .

Table of contents

Why is the research problem important, step 1: identify a broad problem area, step 2: learn more about the problem, other interesting articles, frequently asked questions about research problems.

Having an interesting topic isn’t a strong enough basis for academic research. Without a well-defined research problem, you are likely to end up with an unfocused and unmanageable project.

You might end up repeating what other people have already said, trying to say too much, or doing research without a clear purpose and justification. You need a clear problem in order to do research that contributes new and relevant insights.

Whether you’re planning your thesis , starting a research paper , or writing a research proposal , the research problem is the first step towards knowing exactly what you’ll do and why.

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

As you read about your topic, look for under-explored aspects or areas of concern, conflict, or controversy. Your goal is to find a gap that your research project can fill.

Practical research problems

If you are doing practical research, you can identify a problem by reading reports, following up on previous research, or talking to people who work in the relevant field or organization. You might look for:

  • Issues with performance or efficiency
  • Processes that could be improved
  • Areas of concern among practitioners
  • Difficulties faced by specific groups of people

Examples of practical research problems

Voter turnout in New England has been decreasing, in contrast to the rest of the country.

The HR department of a local chain of restaurants has a high staff turnover rate.

A non-profit organization faces a funding gap that means some of its programs will have to be cut.

Theoretical research problems

If you are doing theoretical research, you can identify a research problem by reading existing research, theory, and debates on your topic to find a gap in what is currently known about it. You might look for:

  • A phenomenon or context that has not been closely studied
  • A contradiction between two or more perspectives
  • A situation or relationship that is not well understood
  • A troubling question that has yet to be resolved

Examples of theoretical research problems

The effects of long-term Vitamin D deficiency on cardiovascular health are not well understood.

The relationship between gender, race, and income inequality has yet to be closely studied in the context of the millennial gig economy.

Historians of Scottish nationalism disagree about the role of the British Empire in the development of Scotland’s national identity.

Next, you have to find out what is already known about the problem, and pinpoint the exact aspect that your research will address.

Context and background

  • Who does the problem affect?
  • Is it a newly-discovered problem, or a well-established one?
  • What research has already been done?
  • What, if any, solutions have been proposed?
  • What are the current debates about the problem? What is missing from these debates?

Specificity and relevance

  • What particular place, time, and/or group of people will you focus on?
  • What aspects will you not be able to tackle?
  • What will the consequences be if the problem is not resolved?

Example of a specific research problem

A local non-profit organization focused on alleviating food insecurity has always fundraised from its existing support base. It lacks understanding of how best to target potential new donors. To be able to continue its work, the organization requires research into more effective fundraising strategies.

Once you have narrowed down your research problem, the next step is to formulate a problem statement , as well as your research questions or hypotheses .

If you want to know more about the research process , methodology , research bias , or statistics , make sure to check out some of our other articles with explanations and examples.

Methodology

  • Sampling methods
  • Simple random sampling
  • Stratified sampling
  • Cluster sampling
  • Likert scales
  • Reproducibility

 Statistics

  • Null hypothesis
  • Statistical power
  • Probability distribution
  • Effect size
  • Poisson distribution

Research bias

  • Optimism bias
  • Cognitive bias
  • Implicit bias
  • Hawthorne effect
  • Anchoring bias
  • Explicit bias

All research questions should be:

  • Focused on a single problem or issue
  • Researchable using primary and/or secondary sources
  • Feasible to answer within the timeframe and practical constraints
  • Specific enough to answer thoroughly
  • Complex enough to develop the answer over the space of a paper or thesis
  • Relevant to your field of study and/or society more broadly

Writing Strong Research Questions

Research questions anchor your whole project, so it’s important to spend some time refining them.

In general, they should be:

  • Focused and researchable
  • Answerable using credible sources
  • Complex and arguable
  • Feasible and specific
  • Relevant and original

Your research objectives indicate how you’ll try to address your research problem and should be specific:

A research aim is a broad statement indicating the general purpose of your research project. It should appear in your introduction at the end of your problem statement , before your research objectives.

Research objectives are more specific than your research aim. They indicate the specific ways you’ll address the overarching aim.

  • Developing a Research Question

by acburton | Mar 22, 2024 | Resources for Students , Writing Resources

Selecting your research question and creating a clear goal and structure for your writing can be challenging – whether you are doing it for the first time or if you’ve done it many times before. It can be especially difficult when your research question starts to look and feel a little different somewhere between your first and final draft. Don’t panic! It’s normal for your research question to change a little (or even quite a bit) as you move through and engage with the writing process. Anticipating this can remind you to stay on track while you work and that it’ll be okay even if the literature takes you in a different direction.

What Makes an Effective Research Question?

The most effective research question will usually be a critical thinking question and should use “how” or “why” to ensure it can move beyond a yes/no or one-word type of answer. Consider how your research question can aim to reveal something new, fill in a gap, even if small, and contribute to the field in a meaningful way; How might the proposed project move knowledge forward about a particular place or process? This should be specific and achievable!

The CEWC’s Grad Writing Consultant Tariq says, “I definitely concentrated on those aspects of what I saw in the field where I believed there was an opportunity to move the discipline forward.”

General Tips

Do your research.

Utilize the librarians at your university and take the time to research your topic first. Try looking at very general sources to get an idea of what could be interesting to you before you move to more academic articles that support your rough idea of the topic. It is important that research is grounded in what you see or experience regarding the topic you have chosen and what is already known in the literature. Spend time researching articles, books, etc. that supports your thesis. Once you have a number of sources that you know support what you want to write about, formulate a research question that serves as the interrogative form of your thesis statement.

Grad Writing Consultant Deni advises, “Delineate your intervention in the literature (i.e., be strategic about the literature you discuss and clear about your contributions to it).”

Start Broadly…. then Narrow Your Topic Down to Something Manageable

When brainstorming your research question, let your mind veer toward connections or associations that you might have already considered or that seem to make sense and consider if new research terms, language or concepts come to mind that may be interesting or exciting for you as a researcher. Sometimes testing out a research question while doing some preliminary researching is also useful to see if the language you are using or the direction you are heading toward is fruitful when trying to search strategically in academic databases. Be prepared to focus on a specific area of a broad topic.

Writing Consultant Jessie recommends outlining: “I think some rough outlining with a research question in mind can be helpful for me. I’ll have a research question and maybe a working thesis that I feel may be my claim to the research question based on some preliminary materials, brainstorming, etc.” — Jessie, CEWC Writing Consultant

Try an Exercise

In the earliest phase of brainstorming, try an exercise suggested by CEWC Writing Specialist, Percival! While it is normally used in classroom or workshop settings, this exercise can easily be modified for someone working alone. The flow of the activity, if done within a group setting, is 1) someone starts with an idea, 2) three other people share their idea, and 3) the starting person picks two of these new ideas they like best and combines their original idea with those. The activity then begins again with the idea that was not chosen. The solo version of this exercise substitutes a ‘word bank,’ created using words, topics, or ideas similar to your broad, overarching theme. Pick two words or phrases from your word bank, combine it with your original idea or topic, and ‘start again’ with two different words. This serves as a replacement for different people’s suggestions. Ideas for your ‘word bank’ can range from vague prompts about mapping or webbing (e.g., where your topic falls within the discipline and others like it), to more specific concepts that come from tracing the history of an idea (its past, present, future) or mapping the idea’s related ideas, influences, etc. Care for a physics analogy? There is a particle (your topic) that you can describe, a wave that the particle traces, and a field that the particle is mapped on.

Get Feedback and Affirm Your Confidence!

Creating a few different versions of your research question (they may be the same topic/issue/theme or differ slightly) can be useful during this process. Sharing these with trusted friends, colleagues, mentors, (or tutors!) and having conversations about your questions and ideas with other people can help you decide which version you may feel most confident or interested in. Ask colleagues and mentors to share their research questions with you to get a lot of examples. Once you have done the work of developing an effective research question, do not forget to affirm your confidence! Based on your working thesis, think about how you might organize your chapters or paragraphs and what resources you have for supporting this structure and organization. This can help boost your confidence that the research question you have created is effective and fruitful.

Be Open to Change

Remember, your research question may change from your first to final draft. For questions along the way, make an appointment with the Writing Center. We are here to help you develop an effective and engaging research question and build the foundation for a solid research paper!

Example 1: In my field developing a research question involves navigating the relationship between 1) what one sees/experiences at their field site and 2) what is already known in the literature. During my preliminary research, I found that the financial value of land was often a matter of precisely these cultural factors. So, my research question ended up being: How do the social and material qualities of land entangle with processes of financialization in the city of Lahore. Regarding point #1, this question was absolutely informed by what I saw in the field. But regarding point #2, the question was also heavily shaped by the literature. – Tariq

Example 2: A research question should not be a yes/no question like “Is pollution bad?”; but an open-ended question where the answer has to be supported with reasons and explanation. The question also has to be narrowed down to a specific topic—using the same example as before—”Is pollution bad?” can be revised to “How does pollution affect people?” I would encourage students to be more specific then; e.g., what area of pollution do you want to talk about: water, air, plastic, climate change… what type of people or demographic can we focus on? …how does this affect marginalized communities, minorities, or specific areas in California? After researching and deciding on a focus, your question might sound something like: How does government policy affect water pollution and how does it affect the marginalized communities in the state of California? -Janella

There is an increasing familiarity with the principles of evidence-based medicine in the surgical community. As surgeons become more aware of the hierarchy of evidence, grades of recommendations and the principles of critical appraisal, they develop an increasing familiarity with research design. Surgeons and clinicians are looking more and more to the literature and clinical trials to guide their practice; as such, it is becoming a responsibility of the clinical research community to attempt to answer questions that are not only well thought out but also clinically relevant. The development of the research question, including a supportive hypothesis and objectives, is a necessary key step in producing clinically relevant results to be used in evidence-based practice. A well-defined and specific research question is more likely to help guide us in making decisions about study design and population and subsequently what data will be collected and analyzed. 1

Objectives of this article

In this article, we discuss important considerations in the development of a research question and hypothesis and in defining objectives for research. By the end of this article, the reader will be able to appreciate the significance of constructing a good research question and developing hypotheses and research objectives for the successful design of a research study. The following article is divided into 3 sections: research question, research hypothesis and research objectives.

Research question

Interest in a particular topic usually begins the research process, but it is the familiarity with the subject that helps define an appropriate research question for a study. 1 Questions then arise out of a perceived knowledge deficit within a subject area or field of study. 2 Indeed, Haynes suggests that it is important to know “where the boundary between current knowledge and ignorance lies.” 1 The challenge in developing an appropriate research question is in determining which clinical uncertainties could or should be studied and also rationalizing the need for their investigation.

Increasing one’s knowledge about the subject of interest can be accomplished in many ways. Appropriate methods include systematically searching the literature, in-depth interviews and focus groups with patients (and proxies) and interviews with experts in the field. In addition, awareness of current trends and technological advances can assist with the development of research questions. 2 It is imperative to understand what has been studied about a topic to date in order to further the knowledge that has been previously gathered on a topic. Indeed, some granting institutions (e.g., Canadian Institute for Health Research) encourage applicants to conduct a systematic review of the available evidence if a recent review does not already exist and preferably a pilot or feasibility study before applying for a grant for a full trial.

In-depth knowledge about a subject may generate a number of questions. It then becomes necessary to ask whether these questions can be answered through one study or if more than one study needed. 1 Additional research questions can be developed, but several basic principles should be taken into consideration. 1 All questions, primary and secondary, should be developed at the beginning and planning stages of a study. Any additional questions should never compromise the primary question because it is the primary research question that forms the basis of the hypothesis and study objectives. It must be kept in mind that within the scope of one study, the presence of a number of research questions will affect and potentially increase the complexity of both the study design and subsequent statistical analyses, not to mention the actual feasibility of answering every question. 1 A sensible strategy is to establish a single primary research question around which to focus the study plan. 3 In a study, the primary research question should be clearly stated at the end of the introduction of the grant proposal, and it usually specifies the population to be studied, the intervention to be implemented and other circumstantial factors. 4

Hulley and colleagues 2 have suggested the use of the FINER criteria in the development of a good research question ( Box 1 ). The FINER criteria highlight useful points that may increase the chances of developing a successful research project. A good research question should specify the population of interest, be of interest to the scientific community and potentially to the public, have clinical relevance and further current knowledge in the field (and of course be compliant with the standards of ethical boards and national research standards).

FINER criteria for a good research question

Adapted with permission from Wolters Kluwer Health. 2

Whereas the FINER criteria outline the important aspects of the question in general, a useful format to use in the development of a specific research question is the PICO format — consider the population (P) of interest, the intervention (I) being studied, the comparison (C) group (or to what is the intervention being compared) and the outcome of interest (O). 3 , 5 , 6 Often timing (T) is added to PICO ( Box 2 ) — that is, “Over what time frame will the study take place?” 1 The PICOT approach helps generate a question that aids in constructing the framework of the study and subsequently in protocol development by alluding to the inclusion and exclusion criteria and identifying the groups of patients to be included. Knowing the specific population of interest, intervention (and comparator) and outcome of interest may also help the researcher identify an appropriate outcome measurement tool. 7 The more defined the population of interest, and thus the more stringent the inclusion and exclusion criteria, the greater the effect on the interpretation and subsequent applicability and generalizability of the research findings. 1 , 2 A restricted study population (and exclusion criteria) may limit bias and increase the internal validity of the study; however, this approach will limit external validity of the study and, thus, the generalizability of the findings to the practical clinical setting. Conversely, a broadly defined study population and inclusion criteria may be representative of practical clinical practice but may increase bias and reduce the internal validity of the study.

PICOT criteria 1

A poorly devised research question may affect the choice of study design, potentially lead to futile situations and, thus, hamper the chance of determining anything of clinical significance, which will then affect the potential for publication. Without devoting appropriate resources to developing the research question, the quality of the study and subsequent results may be compromised. During the initial stages of any research study, it is therefore imperative to formulate a research question that is both clinically relevant and answerable.

Research hypothesis

The primary research question should be driven by the hypothesis rather than the data. 1 , 2 That is, the research question and hypothesis should be developed before the start of the study. This sounds intuitive; however, if we take, for example, a database of information, it is potentially possible to perform multiple statistical comparisons of groups within the database to find a statistically significant association. This could then lead one to work backward from the data and develop the “question.” This is counterintuitive to the process because the question is asked specifically to then find the answer, thus collecting data along the way (i.e., in a prospective manner). Multiple statistical testing of associations from data previously collected could potentially lead to spuriously positive findings of association through chance alone. 2 Therefore, a good hypothesis must be based on a good research question at the start of a trial and, indeed, drive data collection for the study.

The research or clinical hypothesis is developed from the research question and then the main elements of the study — sampling strategy, intervention (if applicable), comparison and outcome variables — are summarized in a form that establishes the basis for testing, statistical and ultimately clinical significance. 3 For example, in a research study comparing computer-assisted acetabular component insertion versus freehand acetabular component placement in patients in need of total hip arthroplasty, the experimental group would be computer-assisted insertion and the control/conventional group would be free-hand placement. The investigative team would first state a research hypothesis. This could be expressed as a single outcome (e.g., computer-assisted acetabular component placement leads to improved functional outcome) or potentially as a complex/composite outcome; that is, more than one outcome (e.g., computer-assisted acetabular component placement leads to both improved radiographic cup placement and improved functional outcome).

However, when formally testing statistical significance, the hypothesis should be stated as a “null” hypothesis. 2 The purpose of hypothesis testing is to make an inference about the population of interest on the basis of a random sample taken from that population. The null hypothesis for the preceding research hypothesis then would be that there is no difference in mean functional outcome between the computer-assisted insertion and free-hand placement techniques. After forming the null hypothesis, the researchers would form an alternate hypothesis stating the nature of the difference, if it should appear. The alternate hypothesis would be that there is a difference in mean functional outcome between these techniques. At the end of the study, the null hypothesis is then tested statistically. If the findings of the study are not statistically significant (i.e., there is no difference in functional outcome between the groups in a statistical sense), we cannot reject the null hypothesis, whereas if the findings were significant, we can reject the null hypothesis and accept the alternate hypothesis (i.e., there is a difference in mean functional outcome between the study groups), errors in testing notwithstanding. In other words, hypothesis testing confirms or refutes the statement that the observed findings did not occur by chance alone but rather occurred because there was a true difference in outcomes between these surgical procedures. The concept of statistical hypothesis testing is complex, and the details are beyond the scope of this article.

Another important concept inherent in hypothesis testing is whether the hypotheses will be 1-sided or 2-sided. A 2-sided hypothesis states that there is a difference between the experimental group and the control group, but it does not specify in advance the expected direction of the difference. For example, we asked whether there is there an improvement in outcomes with computer-assisted surgery or whether the outcomes worse with computer-assisted surgery. We presented a 2-sided test in the above example because we did not specify the direction of the difference. A 1-sided hypothesis states a specific direction (e.g., there is an improvement in outcomes with computer-assisted surgery). A 2-sided hypothesis should be used unless there is a good justification for using a 1-sided hypothesis. As Bland and Atlman 8 stated, “One-sided hypothesis testing should never be used as a device to make a conventionally nonsignificant difference significant.”

The research hypothesis should be stated at the beginning of the study to guide the objectives for research. Whereas the investigators may state the hypothesis as being 1-sided (there is an improvement with treatment), the study and investigators must adhere to the concept of clinical equipoise. According to this principle, a clinical (or surgical) trial is ethical only if the expert community is uncertain about the relative therapeutic merits of the experimental and control groups being evaluated. 9 It means there must exist an honest and professional disagreement among expert clinicians about the preferred treatment. 9

Designing a research hypothesis is supported by a good research question and will influence the type of research design for the study. Acting on the principles of appropriate hypothesis development, the study can then confidently proceed to the development of the research objective.

Research objective

The primary objective should be coupled with the hypothesis of the study. Study objectives define the specific aims of the study and should be clearly stated in the introduction of the research protocol. 7 From our previous example and using the investigative hypothesis that there is a difference in functional outcomes between computer-assisted acetabular component placement and free-hand placement, the primary objective can be stated as follows: this study will compare the functional outcomes of computer-assisted acetabular component insertion versus free-hand placement in patients undergoing total hip arthroplasty. Note that the study objective is an active statement about how the study is going to answer the specific research question. Objectives can (and often do) state exactly which outcome measures are going to be used within their statements. They are important because they not only help guide the development of the protocol and design of study but also play a role in sample size calculations and determining the power of the study. 7 These concepts will be discussed in other articles in this series.

From the surgeon’s point of view, it is important for the study objectives to be focused on outcomes that are important to patients and clinically relevant. For example, the most methodologically sound randomized controlled trial comparing 2 techniques of distal radial fixation would have little or no clinical impact if the primary objective was to determine the effect of treatment A as compared to treatment B on intraoperative fluoroscopy time. However, if the objective was to determine the effect of treatment A as compared to treatment B on patient functional outcome at 1 year, this would have a much more significant impact on clinical decision-making. Second, more meaningful surgeon–patient discussions could ensue, incorporating patient values and preferences with the results from this study. 6 , 7 It is the precise objective and what the investigator is trying to measure that is of clinical relevance in the practical setting.

The following is an example from the literature about the relation between the research question, hypothesis and study objectives:

Study: Warden SJ, Metcalf BR, Kiss ZS, et al. Low-intensity pulsed ultrasound for chronic patellar tendinopathy: a randomized, double-blind, placebo-controlled trial. Rheumatology 2008;47:467–71.

Research question: How does low-intensity pulsed ultrasound (LIPUS) compare with a placebo device in managing the symptoms of skeletally mature patients with patellar tendinopathy?

Research hypothesis: Pain levels are reduced in patients who receive daily active-LIPUS (treatment) for 12 weeks compared with individuals who receive inactive-LIPUS (placebo).

Objective: To investigate the clinical efficacy of LIPUS in the management of patellar tendinopathy symptoms.

The development of the research question is the most important aspect of a research project. A research project can fail if the objectives and hypothesis are poorly focused and underdeveloped. Useful tips for surgical researchers are provided in Box 3 . Designing and developing an appropriate and relevant research question, hypothesis and objectives can be a difficult task. The critical appraisal of the research question used in a study is vital to the application of the findings to clinical practice. Focusing resources, time and dedication to these 3 very important tasks will help to guide a successful research project, influence interpretation of the results and affect future publication efforts.

Tips for developing research questions, hypotheses and objectives for research studies

  • Perform a systematic literature review (if one has not been done) to increase knowledge and familiarity with the topic and to assist with research development.
  • Learn about current trends and technological advances on the topic.
  • Seek careful input from experts, mentors, colleagues and collaborators to refine your research question as this will aid in developing the research question and guide the research study.
  • Use the FINER criteria in the development of the research question.
  • Ensure that the research question follows PICOT format.
  • Develop a research hypothesis from the research question.
  • Develop clear and well-defined primary and secondary (if needed) objectives.
  • Ensure that the research question and objectives are answerable, feasible and clinically relevant.

FINER = feasible, interesting, novel, ethical, relevant; PICOT = population (patients), intervention (for intervention studies only), comparison group, outcome of interest, time.

The Effects of Climate Change

The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere.

explain research questions

  • We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves.
  • Scientists predict global temperature increases from human-made greenhouse gases will continue. Severe weather damage will also increase and intensify.

Earth Will Continue to Warm and the Effects Will Be Profound

Effects_page_triptych

Global climate change is not a future problem. Changes to Earth’s climate driven by increased human emissions of heat-trapping greenhouse gases are already having widespread effects on the environment: glaciers and ice sheets are shrinking, river and lake ice is breaking up earlier, plant and animal geographic ranges are shifting, and plants and trees are blooming sooner.

Effects that scientists had long predicted would result from global climate change are now occurring, such as sea ice loss, accelerated sea level rise, and longer, more intense heat waves.

"The magnitude and rate of climate change and associated risks depend strongly on near-term mitigation and adaptation actions, and projected adverse impacts and related losses and damages escalate with every increment of global warming." - Intergovernmental Panel on Climate Change

Some changes (such as droughts, wildfires, and extreme rainfall) are happening faster than scientists previously assessed. In fact, according to the Intergovernmental Panel on Climate Change (IPCC) — the United Nations body established to assess the science related to climate change — modern humans have never before seen the observed changes in our global climate, and some of these changes are irreversible over the next hundreds to thousands of years.

Scientists have high confidence that global temperatures will continue to rise for many decades, mainly due to greenhouse gases produced by human activities.

The IPCC’s Sixth Assessment report, published in 2021, found that human emissions of heat-trapping gases have already warmed the climate by nearly 2 degrees Fahrenheit (1.1 degrees Celsius) since 1850-1900. 1 The global average temperature is expected to reach or exceed 1.5 degrees C (about 3 degrees F) within the next few decades. These changes will affect all regions of Earth.

The severity of effects caused by climate change will depend on the path of future human activities. More greenhouse gas emissions will lead to more climate extremes and widespread damaging effects across our planet. However, those future effects depend on the total amount of carbon dioxide we emit. So, if we can reduce emissions, we may avoid some of the worst effects.

"The scientific evidence is unequivocal: climate change is a threat to human wellbeing and the health of the planet. Any further delay in concerted global action will miss the brief, rapidly closing window to secure a liveable future." 2 - Intergovernmental Panel on Climate Change

Future effects of global climate change in the united states:.

Here are some of the expected effects of global climate change on the United States, according to the Third and Fourth National Climate Assessment Reports.

U.S. Sea Level Likely to Rise 1 to 6.6 Feet by 2100

Global sea level has risen about 8 inches (0.2 meters) since reliable record-keeping began in 1880. By 2100, scientists project that it will rise at least another foot (0.3 meters), but possibly as high as 6.6 feet (2 meters) in a high-emissions scenario. Sea level is rising because of added water from melting land ice and the expansion of seawater as it warms.

Climate Changes Will Continue Through This Century and Beyond

Global climate is projected to continue warming over this century and beyond.

Hurricanes Will Become Stronger and More Intense

Scientists project that hurricane-associated storm intensity and rainfall rates will increase as the climate continues to warm.

More Droughts and Heat Waves

Droughts in the Southwest and heat waves (periods of abnormally hot weather lasting days to weeks) are projected to become more intense, and cold waves less intense and less frequent.

Longer Wildfire Season

Warming temperatures have extended and intensified wildfire season in the West, where long-term drought in the region has heightened the risk of fires. Scientists estimate that human-caused climate change has already doubled the area of forest burned in recent decades. By around 2050, the amount of land consumed by wildfires in Western states is projected to further increase by two to six times. Even in traditionally rainy regions like the Southeast, wildfires are projected to increase by about 30%.

Changes in Precipitation Patterns

Climate change is having an uneven effect on precipitation (rain and snow) in the United States, with some locations experiencing increased precipitation and flooding, while others suffer from drought. On average, more winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century.

Frost-Free Season (and Growing Season) will Lengthen

The length of the frost-free season, and the corresponding growing season, has been increasing since the 1980s, with the largest increases occurring in the western United States. Across the United States, the growing season is projected to continue to lengthen, which will affect ecosystems and agriculture.

Global Temperatures Will Continue to Rise

Summer of 2023 was Earth's hottest summer on record, 0.41 degrees Fahrenheit (F) (0.23 degrees Celsius (C)) warmer than any other summer in NASA’s record and 2.1 degrees F (1.2 C) warmer than the average summer between 1951 and 1980.

Arctic Is Very Likely to Become Ice-Free

Sea ice cover in the Arctic Ocean is expected to continue decreasing, and the Arctic Ocean will very likely become essentially ice-free in late summer if current projections hold. This change is expected to occur before mid-century.

U.S. Regional Effects

Climate change is bringing different types of challenges to each region of the country. Some of the current and future impacts are summarized below. These findings are from the Third 3 and Fourth 4 National Climate Assessment Reports, released by the U.S. Global Change Research Program .

  • Northeast. Heat waves, heavy downpours, and sea level rise pose increasing challenges to many aspects of life in the Northeast. Infrastructure, agriculture, fisheries, and ecosystems will be increasingly compromised. Farmers can explore new crop options, but these adaptations are not cost- or risk-free. Moreover, adaptive capacity , which varies throughout the region, could be overwhelmed by a changing climate. Many states and cities are beginning to incorporate climate change into their planning.
  • Northwest. Changes in the timing of peak flows in rivers and streams are reducing water supplies and worsening competing demands for water. Sea level rise, erosion, flooding, risks to infrastructure, and increasing ocean acidity pose major threats. Increasing wildfire incidence and severity, heat waves, insect outbreaks, and tree diseases are causing widespread forest die-off.
  • Southeast. Sea level rise poses widespread and continuing threats to the region’s economy and environment. Extreme heat will affect health, energy, agriculture, and more. Decreased water availability will have economic and environmental impacts.
  • Midwest. Extreme heat, heavy downpours, and flooding will affect infrastructure, health, agriculture, forestry, transportation, air and water quality, and more. Climate change will also worsen a range of risks to the Great Lakes.
  • Southwest. Climate change has caused increased heat, drought, and insect outbreaks. In turn, these changes have made wildfires more numerous and severe. The warming climate has also caused a decline in water supplies, reduced agricultural yields, and triggered heat-related health impacts in cities. In coastal areas, flooding and erosion are additional concerns.

A Degree of Difference

So, the Earth's average temperature has increased about 2 degrees Fahrenheit during the 20th century. What's the big deal?

explain research questions

What’s the difference between climate change and global warming?

“Global warming” refers to the long-term warming of the planet. “Climate change” encompasses global warming, but refers to the broader range of changes that are happening to our planet, including rising sea levels; shrinking mountain glaciers; accelerating ice melt in Greenland, Antarctica and the Arctic; and shifts in flower/plant blooming times.

explain research questions

Is it too late to prevent climate change?

Humans have caused major climate changes to happen already, and we have set in motion more changes still. However, if we stopped emitting greenhouse gases today, the rise in global temperatures would begin to flatten within a few years. Temperatures would then plateau but remain well-elevated for many, many centuries.

Q & A With Forensic Nurse, Michelle Patch

explain research questions

Michelle Patch, PhD, APRN-CNS, DF-AFN, FAAN, is an assistant professor at the Johns Hopkins School of Nursing, an adult health clinical nurse specialist, and an advanced forensic nurse. We caught up with Dr. Patch to learn more about forensic nursing and her career and research as a forensic nurse.

Can you explain what forensic nursing is?

Forensic nurses work at the intersection of nursing and the criminal justice and legal system s; they care for patients who have been subject to abuse, violence, criminal activity, liability, and accidents. They conduct evaluations and collect specimens, along with providing care, to support investigations.

One of the most commonly recognized examples of a forensic nurse is a sexual assault nurse examiner. But there are lots of different types of forensic nurses, for example, forensic nurses in the emergency department frequently treat things like gunshot wounds, stab wounds, or wounds stemming from intimate partner violence. We also have nurse coroners who work in death investigation, legal nurse consultants, nurses who work with pediatric or vulnerable adult populations that have experienced abuse, and many more.

Where do you fit in the scope of forensic nursing?

Currently, my primary forensic nursing work is in research. I received my master’s degree from the Johns Hopkins School of Nursing and became an adult health clinical nurse specialist with a forensic focus, then worked in the Johns Hopkins Emergency Department for 10 years as a safety officer.

I came back to get my PhD under my mentor, Jacquelyn Campbell , PhD, RN, FAAN. I studied intimate partner violence, particularly the mechanism of strangulation and how we respond to people who have survived this.

I’m launching a study on acquired brain injury in females who have survived an assault to the head, neck, or face by a partner. The study looks at biofluid biomarkers that might suggest a neurological injury. The idea is that if we can get this information to clinical teams, we can better identify these injuries and more effectively intervene, as many of these patients have repetitive head injuries.

I have also advocated to change policy on strangulation. A couple of years ago, I advocated for a new law that made it a felony in Maryland.

What drew you into nursing as a whole, and specifically forensic nursing? Life experience? Did you become interested later in your nursing career?

I was a Navy nurse and my very first nursing assignment was on a pediatric multi-service ward. I saw many cases of child abuse and neglect. I gravitated to those cases and would even switch assignments with other nurses on the unit. I wanted to be with people at times of intense physical and emotional trauma to support them and help them navigate the health care system.

After September 11, I deployed to Kuwait, and when I returned my husband and I considered our next move (he was also on active duty at the time). It made sense for me to leave the service to have some stability for our family. I heard about this great forensic nursing clinical nurse specialist program at Johns Hopkins, and that’s what I really wanted to do. So that’s how our little family moved to Baltimore.

That interest has always stayed with me. How can I not only care for these patients and families, but also influence policy and generate critical knowledge to guide clinicians? How can we care for them in the best way possible and have positive outcomes?

You were recently named a Distinguished Fellow of the Academy of Forensic Nursing. What does this mean for you?

It’s a great honor. The academy helps me share my work with colleagues and translate my research into practice and policy, which is fantastic. And I’m still in the early stages of my research career, so it’s wonderful to have their support.

It’s also an incredible opportunity to contribute to the forensic nursing field. Most people think of forensic nurses as sexual assault nurse examiners, but through our work with AFN and the Forensic Nursing Certification Board, we have developed and launched certifications for generalists and advanced forensic nursing and are in the process of developing micro-certifications for other forms of abuse and violence.

What trend in forensic nursing has your attention right now?

We are seeing increases in reporting of strangulation as a form of intimate partner violence and sexual violence among the general population. The reason for this is unclear and likely complex, but presents a need for more research in this area. Strangulation can also lead to brain injury from lack of oxygen, and many times assaults that include strangulation also include blunt force trauma to the head, face, or neck.

So, I’ve recently shifted my research focus to brain injury. Existing research centers around male populations, as it often examines people in the military, athletes who play contact sports, and other environments where women are traditionally underrepresented. So there’s this almost hidden group of women that we don’t have a lot of direct research to adequately understand their injuries and guide their care.

Women who experience traumatic brain injury after intimate partner violence don’t have protective gear, training, or other safeguards we associate with traumatic brain injuries, and frequently experience repeated assaults. When we see individuals who are in those situations, we often attribute their symptoms solely to psychological trauma. But if it’s neurological trauma , the treatment needed is different. My work will contribute to the growing information we have about brain injuries from intimate partner violence and hopefully will help inform clinical and legal teams as they care and advocate for this important population.

How does your work shape policy?

Lawmakers need information when they’re developing policy. They’ll ask, “What does the literature say on this?”

Take my work on strangulation, for instance. Many states had not identified strangulation as worthy of a felony charge. I was able to take what I learned from my research and share that with legislators, so they have the information they need to change strangulation’s legal classification.

I’m grateful for the reach my work has had. Recently we filed an amicus brief for U.S. vs. Rahimi, an ongoing Supreme Court case that will determine if a federal law prohibiting firearm possession by people subject to domestic violence protection orders is constitutional. I never thought about contributing to something that would be seen by the Supreme Court, but I’m grateful for the opportunity and experiences that brought me here.

How many fish constitute a school?

Physicists are also interested in fish -- above all when they are researching the formation of structures. A research team from Heinrich Heine University Düsseldorf (HHU) and the University of Bristol (United Kingdom) has examined the schooling behaviour of zebra danio (Danio rerio, also known as "zebrafish") using methods from the field of multi-particle physics. In the scientific journal Nature Communications, they explain that groups of just three fish already move in a similar way to large schools while, by contrast, two fish display completely different behaviour.

The saying "three is a crowd" seems not only to apply to "The Three Investigators" and the three musketeers. In various scientific phenomena -- such as primary colours or spatial dimensions -- three options are also enough to characterise different states.

Physicists have now investigated how various large groups of living creatures behave. They wanted to know the minimum group size needed for the movement patterns of the individual members to change and become a coordinated group movement. And three does indeed seem to be the key number for zebrafish.

The physicists fitted an aquarium in Bristol with synchronised cameras to measure the three-dimensional swim trajectories of their zebrafish. They systematically recorded these trajectories for various group sizes -- two, three, four and fifty fish.

In the next step, they then looked for instances of order in the swim trajectories. They found various movement patterns: The fish either all swam in the same direction or they swam round in a circle together. When they moved in the same direction, they either swam next to each other or one after another.

An isolated pair of fish prefers to move one after another -- one fish leads, the other follows. However, three fish swim next to each other -- it seems that none of them wants to be last. And: This habit of swimming next to each other is also characteristic of a large school of fish.

The researchers then also marked small sub-groups within a large school. They established that groups of three within the school move in a very similar way to an isolated group of three. However, where they only marked two neighbours, they behaved differently in the school than as an isolated pair. Dr Alexandra Zampetaki from Düsseldorf (now Vienna), co-lead author with Dr Yushi Yang of the study now published in Nature Communications, notes: "Practically, three fish form a school, but two are not enough."

"This simple finding initially only applies for zebrafish. However, the concepts could also be transferred to other examples of fauna," says corresponding author Professor Dr C. Patrick Royall from the University of Bristol, who now works at the EPSCI in Paris. Royall continues: "These include schools of other fish such as goldfish or sardines, as well as flocks of birds such as starling murmurations and swarms of insects such as dancing mosquitos."

The idea for the joint research project arose over the course of several visits by Professor Royall, recipient of the Friedrich Wilhelm Bessel Research Award presented by the Alexander von Humboldt Foundation to Professor Dr Hartmut Löwen at HHU. "Applying traditional methods and concepts from the theory of fluids such as pair and triplet correlations to fish was a new challenge, as these concepts originate from the thermodynamic equilibrium and a living school of fish is far from being in a state of equilibrium," says Löwen, Head of the Institute for Theoretical Physics II at HHU.

The fundamental classification of the many-body effects was undertaken in Düsseldorf. In addition, Dr Alexandra Zampetaki simulated the fish trajectories: "We modified our model to enable realistic simulation of the swimming motion of the fish. The simulation confirmed the experimental finding that 'three constitute a school'."

Looking to the future, the researchers are aiming to apply their findings to the group behaviour of people and how they behave for example at parties or mass gatherings. Löwen: "We will see whether the simple limit of the number three then also applies."

Researchers explain the dissimilar smells of babies and teenagers

by Bob Yirka , Phys.org

Researchers explain the dissimilar smells of babies and teenagers

A team of aroma chemists at Friedrich-Alexander-Universität Erlangen-Nürnberg, working with psychologist colleagues from the Technical University of Dresden, has uncovered the reasons for the dissimilar smells between babies and teenagers. The study is published in the journal Communications Chemistry .

Prior research and anecdotal evidence have shown that babies have a pleasant smell, often described as sweet. Teenagers, on the other hand, especially males, have often been described as smelling less pleasant. In this new effort, the research team sought to find out what causes the difference.

The researchers recruited the parents of 18 children aged up to 3 years old to wash the youngsters with a fragrance-free gel and to take swap samples of the armpits of their pajamas prior to sleep. They did the same with 18 teenagers between the ages of 14 and 18. All the cotton pads were then collected and analyzed in a lab setting.

The research team used mass spectrometry to identify the chemical compounds in the pads, and used gas chromatography along with a human sniffer to assess the odorousness of the smells associated with each chemical compound.

The researchers found that most of the chemicals responsible for body odor were similar between the two groups of volunteers. But there were a few that made the difference. Teenage sweat, for example, had high levels of many kinds of carboxylic acids, which the assessors described as "earthy, musty or cheesy."

They also found two steroids in the teen sweat not present in the baby sweat, one of which resulted in "musk or urine-like" emanations—the other, the assessors suggested, smelled more like "musk and sandalwood." Without such chemicals, the sweat of babies smelled much sweeter.

The researchers suggest that study of the chemical compounds in teen sweat could prove fruitful for makers of odor-control products. They also suggest that more work could done to better understand the impact of such odors on parents .
