Use of biographical inventory in the Air Force classification program

Abstract

Product-moment correlations were computed between the scores on eight Biographical Inventory keys and final grades from 24 Air Force technical schools. The size of samples varied from 49 (stenographer) to 1731 (clerk typist). The correlations are cross-validities since the 8 keys were developed on prior samples to those used here. The correlations range from -.28 to .61. Since the median intercorrelation between the 8 keys is low (.26), the Biographical Inventory makes a substantial contribution to differential classification over and beyond the increase in predictive efficiency for the various criteria.
