Hi, yet another question from me.
Can anyone tell me what analysis (and how many?) to perform in the next situation:
3 different study groups (I want to know the possible difference between all three). One dependent variable (interval), measured 3 times, over time.
Also taken into account co-variables: age, IQ and sex.
I was thinking two-way ANOVA with repeated measures, but is that correct? And where to fill in what? And how to perform the analysis?
I hope one of you guys can help me! Thnx!!
