Moderation effect size

Post by gabor »

Hi,


When calculating effect size (f square) for a moderating effect, should the R-square-without-the-moderator exclude the direct effect of the moderator variable too, or just the effect of the IV x Moderator?

I can't seem to answer this based on Henseler & Fassott (2010), Section 30.5.2.


Thanks

Hi,

When you calculate the effect size for a moderating effect you just delete the effect of the IV x Moderator path.
