We are trying to use G power to calculate the sample size in an experiment that will be repeated on two separate days. We will have 6 groups and will repeat the exact same study with another 6 groups on a second day. For Power calculations are we doing an Anova with repeated measures between factors or ANOVA repeated measures within factors?
Also do we specify 6 groups or 12 groups (i.e count over both days)?

  • $\begingroup$ "We will have 6 groups and will repeat the exact same study with another 6 groups on a second day." It seems you will get the measurement (response variable) one time from each subject. If it is true, then you do not have repeated measurement. $\endgroup$ – user158565 Dec 10 '18 at 16:27
