Hi all,
Is there any consensus on computing effect sizes for multilevel models?
Should I use the SD's for the unconditional model, the child SD (for student-level variables), and the class SD (for classroom-level variables)?
My thought is that using classroom SD will tend to inflate effect sizes, but I could be wrong.
