Hi ElMaestro,

❝ ❝ 3. 2 group parallel

❝ ❝    Only the pooled (total) s²_p. With a tricky mixed-effects model you

❝ ❝    could get s²_pT and s²_pR.

❝

❝ This tricky model […] may be overkill. I believe you will get the same result as you would obtain from doing a plain sample standard deviation on T and R subsets, respectively.

KISS. You are absolutely right.
