In G power 3, ANOVA repeated measures within-between interaction: Only the total sample size is reported assuming equal sample size for the two groups.
My questions are:
- How would it work if the sample sizes are slightly different, for example: N1/ N2 = 1.16.
- I have to input correlation between repeated measures. Is this the correlation between repeats after merging the data from the two groups?
- Information about non-centrality parameter would be helpful.
