Sample Correlation Coefficient

A numerical value that determines both the magnitude and direction of a straight-line association between two variables measured quantitatively in a given sample.

Dependent Variable

The outcome factor whose variations are studied to determine the effect of one or more independent variables.

Independent Variable

A variable presumed to influence or determine the value of another variable, often called the dependent variable.
