I have 3 intervention groups: G1= 2nd and 4th grade children G2 = 2nd and 4th grade children G3 = 2nd and 4th grade children Firstly, I wanted to check the assumptions, but between which groups do I need to check the assumptions (normality, homegeinety of variance, etc) 2nd and 4th grade children? or G1, G2 and G3? Thanks a lot, Nuria Author Posts Viewing 1 post (of 1 total) The forum ‘Default Forum’ is closed to new topics and replies.
