Yes, I mean a standardized mean difference or a difference between
proportions. In many studies, participants' results are based on a
different number of trials.
Subject: [R-meta] N of trials or participants?
When and how is it possible to use N of trials instead of N of
participants in the standardized effect sizes estimation?
It is likely that this question already had a response. In this case,
please send me links or references.
