eta squared

(symbol: η2) a measure of the amount of variance in a dependent variable that can be explained by one or more independent variables, as calculated in a variety of statistical procedures. In an analysis of variance, for example, eta squared is calculated as the sum of squares for the treatment (i.e., sum of squared differences between a group mean and the grand mean) divided by the total sum of squares. Eta squared is often used as an effect size measure.
