Definitions:

Correlation

A statistical measure that indicates the extent to which two variables fluctuate together, without necessarily implying causation.

Independent Variable

The variable in an experiment that is manipulated or changed by the researcher to investigate its effect on the dependent variable.

Dependent Variable

The variable in an experiment that is expected to change as a result of manipulations to the independent variable.

Self-Reports

Direct reports or accounts from individuals about their own feelings, behaviors, or attitudes, often used in research.
