Abstract
VALCOR is a Turbo-Basic program that corrects the observed (uncorrected) validity coefficients for criterion and predictor unreliability and range restriction in the predictor. Furthermore, using the formulas for the standard error of functions of correlations derived by Bobko and Rieck (1980), the program provides an estimation of the standard error, the confidence intervals, and the probability of the corrected validity coefficients. In this way, the probability and the boundaries of the corrected validity coefficients may be reported together with the probability of the uncorrected validity coefficients. The results are presented on the computer screen and may be saved in an external file.
