Hi all! I'm hoping for some help with reviewer comments on a paper. I'm a grad student in behavioural neuroscience, with some stats courses under my belt but nothing very helpful!
The issue is this: I have two groups (high and low on a measure), and I am comparing them on 12 different behaviours (both duration and frequency) - so 24 DVs. I am also comparing the gene expression between groups for 8 brain areas and 8 genes - so 64 DVs for this part.
The reviewers have requested a correction be made for using the multiple comparisons. However, Bonferroni (the one I know how to calculate by hand!) is WAY too conservative and ends up wiping out all my significance. I've spent the last 5 hours trying to find something that works that I can understand, and so far no luck.
Is there another correction that I can use that's more reasonable (i.e., less conservative)? I have access to both SPSS and SigmaStat, so if possible using one of these would be preferable. I can also handle fairly simple manual calculations as long as they're easy to apply to all my tests.
Thank you!!!!
