Abstract: | Evaluated the statistical power of the Callender-Osburn method for testing the situational specificity hypothesis in validity generalization studies. The Schmidt-Hunter 75% rule for testing the situational specificity hypothesis was also studied with regard to its sensitivity for detecting both Type I and Type II errors. Results show that both the Callender-Osburn procedure and Schmidt-Hunter 75% rule lacked sufficient statistical power to detect low-to-moderate true validity variance when sample size was below 100.
