I conducted the following mixed ANOVA with a covariate:

2 x groups (BS factor)

3 x Switching as repeated measures (WS factor)

IQ as covariate.

My output gave me the following results:

in the BS-table, the effect of IQ and group x IQ was not significant. Which is good, I guess. not so nice is that the main effect of groups is also non-sign.

WS table:

- Main effect of switching not sign.

- switching x covar. not sign. (which is good I guess!)

-switching x group significant (apparently the result of your switching depends on which group you are in)

- SIGN group x switching x IQ interaction!!!!

What do I do with this? I could not find any help online on this matter. Does that mean that IQ confounds the interaction of switching x group???

I am really stuck on this problem, any help is appreciated!!
