Abstract | An index that reflects the accuracy of selection associated with a predictive validity of "r" is presented. Based on Sheppard's thoerem on median dichotomies, it is a measure of improvement over chance assignment to "accept" (or "reject"). Because the index is a measure of the accuracy of this assignment, rather than of variation from prediction throughout the distribution, the index is deemed to be a more appropriate measure than r squared or indices based on r squared when the purpose of testing is selection or placement.
