[Eeglablist] ANOVA and Bonferroni_eeglab vs. SPSS

[Wind, Johanna]

Hello everybody,

I've got a question in relation to the eeglab output. Does eeglab use the same computation of ANOVA and Bonferroni-correction like SPSS does? When I transfer the specdata from eeglab to SPSS and compute an ANOVA with post hoc tests in order to get pairwise comparisons between my conditions, there were given significant differences. But in the pairwise comparison of the conditions in eeglab are not all electrodes significant like shown in SPSS.

For clearer understanding here a short overview of my study design:
There were 4 conditions and 2 testing times (pretest and posttest) with 19 electrodes. I computed a pairwise comparison between the conditions and the testing times. There were significant differences between the conditions in SPSS, but not so in eeglab.



It would be awesome, if you can reply my questions.
