If one variable is thought of as the predictor and another variable as the criterion, we can square the correlation coefficient to interpret the strength of the relationship. The square of the correlation (r2) gives the proportion of criterion variance that is accounted for by its linear relationship with the predictor.

The value of the Correlation Coefficient indicates the strength of the linear relationship between 2 variables. The following diagram gives a guide to the strength of the correlation based on the value of ‘r’. EXAMPLES.

Correlation is used in describing the strength of the relationship between two (or more) variables. It varies from a low of -1 (perfect negative correlation) to +1 (perfect positive relationship). A value of 0 means there is no correlation
