Partial Eta Squared Spss. Partial eta 2 frac ss effect ss effect ss error. Spss only reports partial eta squared and in earlier versions of the software it was unfortunately labeled eta squared.
Most researchers will agree this makes more sense. P sig in spss tells us the likelihood of some effect being zero in our population. In anova we always report the f value degrees of freedom df and p for each effect possibly just one for one way anova.

One that s often used is partial eta squared denoted as η 2 η is the greek letter eta. If you really really want to know. Partial eta squared ssfactor ssfactor sserror so that s the proportion of variance that some factor could have accounted for. However part of sstotal may already be accounted for by a different factor when there s more than 1 factor involved.
