Hi.

I was just wondering if someone could help clarify something I have become rather confused about. At what point (if any) do you need to use a Bonferroni correction when using a one way independant ANOVA? I was under the impression that this was only necessary with a T test but my tutor has told me I need to use one with an ANOVA.

Thanks in advance

It's done on post-hoc tests after the initial ANOVA, when you are doing a lot of comparisons and you want to protect against an escalating Type I error rate.
