Correlational Measures

Statistical methods used to determine the extent to which two variables have a linear relationship with each other.

Correlation Coefficient

A statistical measure of the extent to which two factors vary together, and thus of how well either factor predicts the other. Scores with a positive correlation coefficient move up and down together (as with high school and college GPAs). A negative correlation coefficient indicates that one score falls as the other rises (as in the relationship between self-esteem and depression).

Statistical Measure
