Hi Everyone,
I have 2 groups and 2 conditions. I looked at the interaction between the group and condition(GroupAvGroupB x Condition1vCondition2);
However, I would like to see if these results hold after factoring out or controlling for a possible covariate (such as Age)
So I want to look at Group A vs Group B x Condition 1 vs Condition 2 - while controlling for covariate.
Can anyone suggest how I should do this?
Best,
Arthur
