[Eeglablist] Stat test for eeg data

[Haneen Alsuradi]

Dear All

I have a question regarding a statistical testing methodology for eeg data.

I conducted an experiment where i have recruited people to go through three
conditions.

I know the frequency bands of interest based on literature.

I found the region of interest (spatial) using a data driven approach.

Given this region of interest, I averaged over channels within the region
(power values in dB). I conducted pair wise statistical comparisons between
the conditions (three in total) using the bootstrapping test. I corrected
for the three pvalues using fdr. Please note that my data violates
normality.


I would like to seek advice if this is a valid approach, or if this is too
lenient of a method? Would using friedman test followed by bonferroni is a
more appropriate method? Or is bootstrapping test is equivalently suitable?
I read on eeglab documentation that bootstrapping test is ideal for eeg
data. Is the way I described for using it sensible?

Please advise and share your thoughts.


Best
Haneen
