A more valid method of comparing the accomplishment quotients of individual pupils with those of the group

Abstract

"Since the usual technique yields an expected accomplishment quotient too high for bright pupils and too low for those who are dull, the proposed method operates to make the expected AQ dependent upon the capacity and achievement of the group rather than of some theoretical norm. Thus bright pupils will be expected to have accomplishment quotients of less than 100, while dull pupils will be expected to have those of more than 100. The expected AQ may be computed from a regression line of IQ on AQ." (PsycInfo Database Record (c) 2025 APA, all rights reserved)
