How to Use SPSS: Two-Way ANCOVA

[@TheLincCage]

Thanks for the video. Can you explain what the univariate tables show/mean?

[@tacappaert]

This is additional information about the effect each factor has on it's own.

Is there a way to use a one-way ANCOVA with repeated measures? Ive looked everywhere and I cannot seem to find. I want to give a rational as to why one way ANOVA with repeated measures was used vs ANCOVA

[@tacappaert]

Yes, you could perform a one-way ANCOVA using a post-test as your outcome and the pre-test as your covariate. You could use a change score (e.g. difference between pre- and post-test) as your outcome and then whichever covariate you choose. You could also use ANCOVA with your time factor as one IV and group as your other IV.

+HEMA VENKAT Traditionally they are not, but I have used them in an ANCOVA.
