Explanation:

To differentiate independent and dependent variables, just remember that the dependent variable is not changed by the researcher. It changes depending on the independent variable. in short, it is what is being tested on. The independent variable on the other hand, is manipulated by the researcher to elicit a change in the dependent variable.
