Thanks a lot, Gerardo, Anderson University Women's Basketball Division, Eta squared 2 (part of the r family of effect sizes, and an extension of r 2 that can be used for more than two sets of observations) measures the proportion of the variation in Y that is associated with membership of the different groups defined by X, or the sum of squares of the effect divided by the total sum of squares: That is, SS is the sum of squares as the equation Eta2 = SS / SS stands for the square amounts. Eta squared can be calculated as =r=chi/N. The formula is the same as the one from Caroll and Nordholm (1975, p. 547) just written slightly different. Partial Eta-Squared. This measure of effect size can be extended to the omnibus ANOVA. I believe that ((n-k)*e)/(1-e) = r^2*n*(k-1)/k https://www.real-statistics.com/anova-repeated-measures/repeated-measures-anova-tool/ If p > 0.05, equal variances can be assumed. The group means differ on average by d standard deviations from the grand mean. Both of these measures concern the entire model. We will usethis measure of effect size when we discuss power and sample size requirements (see Power for One-way ANOVA). I am also using XLStat to run one-way ANOVA and that also does not show a number in that space. To test this, we recruit 30 men and 30 women to participate in an experiment in which we randomly assign 10 of each to follow a program of either no exercise, light exercise, or intense exercise for one month. Is is possible to use this analysis to determine if the categories are statistically different or similar to one another?
