I'm following an SPSS guide online, and the procedure is to first test for a three-way interaction. In my case there was no sig. three-way interaction. Then the procedure asks me to consider two-way interactions. However, the guide says if I do not have any sig. two-way interactions, then I can stop the analysis there. Why? How come I don't consider the main effects of each factor individually? In a two-way ANOVA, you consider both the interactions and the main effects.

Either you are misreading the guide or the guide is wrong. What you are saying makes no sense. Can you post a link to the guide or give an exact quote of the passage?

$\begingroup$ Yes, it doesn't make sense. That's why I'm asking. Screenshot: imgur.com/a/Q3w6i. $\endgroup$ Commented Jul 2, 2015 at 11:32

$\begingroup$ That looks like someone made a typo. Or maybe it's just an error. $\endgroup$ Commented Jul 2, 2015 at 12:28
