thanks a lot for your perfect video! I was searching all the youtube for sth like this! and am watching all of your videos. many thanks. btw, a short question; what if we would like to predict effect size for sample size calculation? I think we can consider two of those cells in ANOVA which are thought to be of the least difference, so we would calc Cohen's D for them to get the most conservative n per group. am I right?
Instead the Omega square formula, can’t we use the Eta square?
