Eta-squared one-way repeated measures anova

Souaze

Hello,

I think there is an error in eta square in one-way repeated measures anova. Jamovi doesn't give the same result, and I think Jasp is wrong.

There is the same problem in two-way repeated measures anova, but not in mixed anova.

Thanks,

EJ

I suspect this is an old issue related to whether or not to pool an error term, but I've asked a team member just to be sure. Regardless, thanks for bringing this up.
