Hi Hötzi,

❝ 3. 2 group parallel

❝    Only the pooled (total) s²p. With a tricky mixed-effects model you could

❝    get s²pT and s²pR.


2 group parallel: This tricky model may not be so tricky after all, but 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.

Pass or fail!
