Re: [Freesurfer] Unequal size groups

We do not offer anything special for this. The difference in group size is not an issue in and of itself. The only problem that would arise is if the groups have different variances.

Hi

I’m using fs-fast to map the connectivity differences between 3 groups. My problem is unequally sized groups. In the sense that the first group consists of 40 subjects, the second of 190, and the third of 18. What solutions does FreeSurfer offer to handle this type of problem which affects the assumption of equal variances in tests like ANOVA?

Thanks

Stefano
