Hello,
We're having trouble running a paired t-test in SPM5. In our design, we have two conditions, A and B, and for each subject, we generated contrasts for A > B and B > A. We ran these subjects twice and want to compare 1st scan (A > B) > 2nd scan (A > B) and vice versa, so we used a paired t-test. However,
1st (A >B) > 2nd (A >B) equalled 2nd (B >A) > 1st (B >A), and
1st (B > A) > 2nd (B > A) equalled 2nd (A > B) > 1st (A > B).
Do you know what we did wrong?
Thank you for any help.
Andrew
