Correlation Coefficient Calculation
A correlation coefficient is a numerical measure of some type of correlation, meaning a statistical relationship between two variables.
A statistic used to show how the scores from one measure relate to scores on a second measure for the same group of individuals. A high value (approaching +1.00) is a strong direct relationship, a low negative value (approaching -1.00) is a strong inverse relationship, and values near 0.00 indicate little, if any, relationship.
