Oh, thank you. This was immensely useful. I now will pick some other object of study, and limit myself to a few tests (about 8). I kinda suspected I'll have to obtain data for as many populations as possible, to estimate between-population variation, and for as many trial specimens as possible, but I didn't know exactly how to check it for efficiency. Happy winter holidays to you!
I think it's past time for another Stupid Questions thread, so here we go.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Please respect people trying to fix any ignorance they might have, rather than mocking that ignorance.
