Definitions:

Correlation Coefficient

A measure ranging from -1 to 1 that indicates the strength and direction of the relationship between two variables.

Multiple Correlation

A mathematical method used to evaluate how strong the association is between one dependent variable and multiple independent variables.

Criterion Variables
