The drill/test correlation report
calculates the Pearson correlation coefficient between Drill results and test results from members of a group. It predicts whether a participant will perform well on a test based on the control they have over the content of the corresponding drill.
The Pearson correlation coefficient goes from 0 - 1. This rule applies: The higher the coefficient, the higher the predictive value of the drills over the test results.
