Rather use "Max" Values or "Mean" to reduce complexity of TFR ANOVA

Hi everyone,

I know this is not a MNE specific question, but I dont know where to turn to otherwise

I calculated TFRs and I had 4 factors, with one being different electrode clusters. The reviewer asked to reduce complexity of the ANOVA by either a priori select an electrode cluster or post hoc by grand averaging over all conditions.

If I decide to do the post hoc grand average - Is it more appropriate to go for the cluster that shows the highest maximum or with the one with the highest mean value?

Thank you so much!!
