Abstract

Criterion scaling is a technique for scaling questionnaire item responses so as to maximize their correlation with an external criterion. The correlation between the criterion and the scaled item is equal to the correlation ratio or 7 coefficient. The results of rescaling the ninth grade questionnaire of the "Equal Educational Opportunity Survey" is presented and compared to the subjective scaling used in the Report. Criterion scaling increased all correlations but the change is not substantial enough to change the interpretation of the Report.
