For example, if you are investigating the relationship between corporate environmental sustainability efforts [the independent variable] and dependent variables associated with measuring employee satisfaction at work using a survey instrument, you would first identify each variable and then provide background information about the variables.

8. Independent & Dependent Variables (With Examples)

While the independent variable is the " cause ", the dependent variable is the " effect " - or rather, the affected variable. In other words, the dependent variable is the variable that is assumed to change as a result of a change in the independent variable. Keeping with the previous example, let's look at some dependent variables ...

9. Types of Variables in Psychology Research

By systematically changing some variables in an experiment and measuring what happens as a result, researchers are able to learn more about cause-and-effect relationships. The two main types of variables in psychology are the independent variable and the dependent variable. Both variables are important in the process of collecting data about ...

10. 2.2: Concepts, Constructs, and Variables

As shown in Figure 2.1, scientific research proceeds along two planes: a theoretical plane and an empirical plane. Constructs are conceptualized at the theoretical (abstract) plane, while variables are operationalized and measured at the empirical (observational) plane. Thinking like a researcher implies the ability to move back and forth ...

15. Types of Variables, Descriptive Statistics, and Sample Size

A variable is an essential component of any statistical data. It is a feature of a member of a given sample or population, which is unique, and can differ in quantity or quantity from another member of the same sample or population. Variables either are the primary quantities of interest or act as practical substitutes for the same.

21. The Independent Variable vs. Dependent Variable in Research

The independent variable, often denoted as X, is the variable that is manipulated or controlled by the researcher intentionally.
