Eta squared is a measure of effect size that is commonly used in ANOVA models. Additionally, the confidence intervals produced here will differ from the confidence intervals produced in the OLS section. It is a commonly used estimate of effect size, but it is a biased estimate of the populations coefficient of determination and so omega-square is a better estimate. In other words, it is a statistical method to measure the relationship between two variables from a different group of data sets. Small, medium, and large are relative terms. He has been writing tech tutorials for over a decade now. (I checked all figure 3 for the ACNOVA sections and none seem to line up). The eta squared is the proportion of the total variability in the dependent variable that is accounted for by the variation in the independent variable. You can check it out here.
