You are an excellent teacher.

Thank you Professor. Just saw on LinkedIn that you retired! Congratulations and have a great time ahead!

Awesome explanation. I am assuming that you would continue with a post hoc, ie Tukey's. Does SPSS report the Omega squared value? Thanks!

[@jesischwarz2978]

The SPSS report does include an effect size value.

it seems reasonable to add, that omega^2 is proper, when groups are the same size
