The estimation of the standard deviation of the dollar value of performance in a complex military occupation : a comparison of methods

Abstract

A major impediment to the application of the Cronbach-Gleser model for estimating the utility of personnel selection programs, has been the difficulty encountered in accurately estimating the standard derivation of the dollar value of performance (SDy). The estimates made using the Schmidt et al. and modified procedure showed little convergence with estimates made using the Superior Equivalence and 40% procedures. The latter procedures produced similar estimates which were higher than those made using the first two procedures. The assumption of normally distributed performance was not supported in the study. This and other findings, indicate the need for further research in several areas before widespread use of any of the estimation procedures is adopted. -- Abstract shortened
