Higher Order Factorial Designs

#1
Hi There,

I don't have a specific homework question. I was wondering, however, if any kind person could point me out to a website or book perhaps... that explains how to find main effects and interactions by residualizing group means, for higher order factorial designs. I understand 2x2, etc... but when you get that third factor in there, that's where I lapse off. Thanks so much in advance for any help! :)

by residualizing group means? - could you explain what you mean here?

There are plenty of good textbooks that lay out the formulas for 3-factor ANOVAs.
