Dear FSLers,
We compared the GM, volumetric abnormalities between 3 groups of subjects in an ANOVA design using TFCE based thresholding, at .05. However we did not find any differences between two of the 3 groups. We are now trying to understand if this was due to our sample sizes.
The previous posts on this list were not helpful, probably bec of my level of knowledge in statistics.
Could you please guide me to do this power analysis ?
Thank you,
Sinan
