Hi,
I have a question that I have a lot of difficulties concerning statistics. Indeed, I extracted the FA values between 2 experimental conditions. I have paired comparisons between pretest-posttest with my 2 Regions of interest to the two hemispheres. I would like to know if in my case I have to correct my p-value. Do I "necessarily" have to divide my p value by 4 although these are areas that are part of my hypotheses a priori?
Thank you in advance for any help and your time
