Anyone used G*Power before

S

Hi there,

Ive been asked to use G*power to determine sample sizes for a range of analyses. However, I have absolutely no idea how to use it. Has anyone used it before and can anyone recommend any books/online material that will help me understand what I need to do.

thank you! x

Used it for the first time today to calculate sample population needed for study with known effect size. All appeared fairly intuitive. Pm me and I'll give more detail.
