Estimates of the dollar value of employee output in utility analyses: An empirical test of two theories

Abstract

Examined distributions of estimates of the dollar value of performance in studies employing the method of F. L. Schmidt et al (1979) for estimating the standard deviation of job performance ( SD y ) and found evidence that (1) the mean 50th percentile estimate is biased downward, (2) estimates of SD y appear to be a constant percentage of the 50th percentile estimate, and (3) estimates of SD y as a percentage of the 50th percentile value ( SD p ) are quite similar to empirical SD p values based on actual employee output. These findings suggest that the downward bias in the mean estimate of the 50th percentile causes the mean estimates of SD y to be similarly biased downward, but does not bias the estimates of SD p . Finally, an objective method for estimating the value of average employee output is described. The product of this value and the mean supervisory estimate of SD p yields an unbiased estimate of SD y . (PsycInfo Database Record (c) 2025 APA, all rights reserved)
