I am planning a within-subjects study with four different conditions and I am using G*Power to calculate my needed sample size. Not being intimately acquainted with the intricacies of statistics in general (and repeated measures ANOVA in particular) what are some good assumptions for the correlation among repeated measures and nonsphericity correction values? What can I base these values on rather than guesswork?
