WebApr 16, 2024 · as you noticed, the "f" for GPower 3.0 is very different. This is because correlation is not incorporated directly, but it is part of the formula (thus, it must be explicitely defined, because it is necessary to calculate the non-centrality parameter). The formula is shown in the paper's Appendix. WebYes, you did. The "Total sample size" in g*power is for overall N. You would divide that by how ever many groups are in your study; in your case 2. Effect size should be chosen based on studies in the area that you are researching. You would want to model the average effect size typically found in the literature.
