Hi sorry I know this doesn't relate to this. What would be a minimum number of samples if comparing 2 or 3 groups in a study. For example if I had 3 groups of 20 samples is that enough to draw an accurate 95 confidence result from a t test? Thanks 😊

The math interests me. Unfortunately I've got VR bombs goibg off all around me. So i could only focus for a minute before losing concentrateion on it
