Dear Expert
I have 2 groups. (group 1 and group 2)
And I'd like to see how age effect differs between groups.
So I chose 2 sample T test.
And the Covariate: Name=age. Interactions=with factor 1
The design graph becomes: group 1, group 2, age@sF21, age@sF22
And the contrasts I used are: 0 0 1 -1 and 0 0 -1 1.
Hope that's okay?
Thanks!
