Hello AFNI team (probably Gang smileys with beer),

If you are performing a t-test (3dttest++ for example) between two groups of old and young age.
Would you add age as a covariate?
I would bet not since age is not independent of the 2 variables tested right?
I just wanted to be sure,
Thank you
Clément
