Dependent variable in research example

    • How do you identify independent and dependent variables?

      An independent variable is a variable that does not depend on anything. It is manipulated to determine the value of a dependent variable. The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation and the independent variables are the inputs to that measurement.

    • What are some examples of independent and dependent variables?

      Here are several examples of independent and dependent variables in experiments: In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the ...

    • What are the different types of variables in research?

      Types of Variables - The following website provides a straightforward discussion regarding the different types of variables in research studies including definitions, comparisons, and specific examples. The types of variables discussed are dependent/independent, experimental/non-experimental, and categorical/continuous.

    • What is an example of a dependent variable in an experiment?

      Scientists do not manipulate the dependent variable in an experiment. An example of a dependent variable is the test score of a student; the independent variable for an experiment investigating that might be the amount of time a student has to revise.

And we have explanatory variables: X1, X2, X3. In Stata we use the GLM command. Y is the dependent variable as a function of these three independent variables.
