Hi
I have two groups and one psychological scale.
So the GLM design is:
EV1= group A ( so subjects in group A get 1, and subjects in group B get 0)
EV2= group B ( so subjects in group A get 0, and subjects in group B get 1)
EV3= age ( I demeaned this EV)
EV4= gender ( I demeaned this EV)
EV5= psychological scores for group A ( I demeaned EV5 and EV6 together and separated them apart to EV5 and EV6 )
EV6 = psychological scores for group B
But do I really need EV1 and EV2? I already have EV5 and EV6???
THANKS a lot!!!
