As I forgot to ask my supervisor yesterday.
I have run a MANOVA on two DVs, and in the Multivariate Tests table it says that the main effects of Group and Time are not significant, but that the interaction effect is (Group x Time).
I conducted a pre-post intervention study, so I do want a significant interaction effect to show that there was a change in the groups over time.
But I am confused whether I need also to have the main effects of either Time or Group (or both) to be significant.
Does anyone know??
Thanks
