Prediction of college scholarship for groups having effort indices of restricted range

Abstract

Effort indices (E. I.) were computed for 196 freshmen entering New York University by finding for each the ratio of high school marks to aptitude score. Correlations were then computed between first-year college marks and aptitude for subgroups within various restricted ranges of E.I. "The more homogeneous a subgroup was with respect to high school E.I.'s, the higher was the relationship between aptitude and college scholarship." Students with high E.I.'s performed closely in accordance with aptitudes, while performance of students having low E.I.'s was much less predictable from aptitude scores. E.I. was found to be relatively constant; intercorrelations between E.I.'s computed on the basis of high school, Regents, and college marks, respectively, ranged from .676 to .719.
