aPartial eta squared is SS effect/(SS effect + SS error) where SS effect is the sum of squares for the main or interaction effect and SS error is the sum of squares for the error term. It indicates the proportion of variance of the dependent variable that is accounted for by a particular main or interaction effect.
bTotals are corrected for degrees of freedom, therefore they are not the sum of squares.
