I have conducted a G power analysis for repeated measures (ANOVA) for the calculation of sample size (N). Does 'N' represent the minimum sample size? Also, since there are 2 groups, does that mean that each group needs to have exactly 50% participants (N/2) as calculated from the sample size? What if the proportion is skewed but N remains the same?
The G*Power software supports sample size and power calculation for various statistical methods (F, t, χ2, z, and exact tests). This software is helpful for researchers to estimate the sample size and to conduct power analysis.
