Effect size for ANCOVA?

Hi everyone,

Maybe I'm not looking in the right places, but I'm having a really hard time finding out how to do an effect size for ANCOVA in SPSS. Is this even a possibility? I have found some guides to do it in Excel, but I don't really understand them and was really hoping there is a way to go about this in SPSS.

I ran two ANCOVAs and I want to see how the effect size differs for each one - does anyone have advice about this?

Thank you so much!

doesn't it spit out some kind of eta-squared / partial eta-squared kind of thing somewhere? i've seen it at the bottom of the box where you see if your factors are significant or not
