Controlling for familywise error for large correlations matrix


New Member
Hi there,

I have 24 variables that I am currently running spearman's rank order correlations on in SPSS 19. I have read up a bit on familywise error and false discovery rate (e.g. but still do not have a clear idea on how implement controls against the increased risk of type I error. I believe that I should be adjusting my p levels but do not really know where to start. Any advice would be much appreciated.
