Averaging Untransformed Variance Ratios Can Be Misleading: A Comment on Feingold.
Katzman, Steven; Alliger, George M.
Review of Educational Research, v62 n4 p427-28 Win 1992
Reanalysis of A. Feingold's examination of variability differences between males and females on several nationally normed cognitive test batteries does not yield substantially different conclusions, but the method of averaging variance ratios exaggerates the differences in male and female variability. Simply averaging ratios of variance can lead to illusory conclusions. (SLD)
