Estimation of [Omega Squared] for a One-Way Fixed-Effects Model When Sample Sizes Are Disproportionate.
Wang, Marilyn D.
Educational and Psychological Measurement, v42 n1 p167-79 Spr 1982
Formulas for estimating the population measure of effect strength are based on the assumption that sample sizes are proportional to the sizes of their respective treatment populations. Because this assumption is frequently violated, a general method of estimating effect strength for the one-factor, fixed-effects design is presented. (Author/BW)
