Since the sum of squares total is smaller in Study 1, it implies that there is less variability in the data. Therefore, any effect size in Study 1 will be larger as compared to Study 2. Additionally, since the sum of squares for Factor A is the same in both studies, the effect size will depend solely on the sum of squares total, making Study 1 the best choice for a larger effect size.
