The Overestimation of Effect Sizes from "F" Values in Meta-Analysis: The Cause and a Solution.
Hullett, Craig R.; Levine, Timothy R.
Communication Monographs, v70 n1 p52-67 Mar 2003
Notes that because estimates of effect sizes are often either misreported or not reported at all, meta-analysts must use conversion formulas that allow estimates of effect sizes from information available. Focuses on formulas that convert "F" in ANOVA, a statistical test, to eta-squared, "d," or the correlation equivalent. Demonstrates that the traditional "F to r" formula can inflate estimates of effect sizes. (PM)
