Dear ElMaestro!

❝ That table doesn't seem intuitive to me. The variability estimate should generally go down with increasing sample size, shouldn't it?. Perhaps I misunderstood some of your underlying ideas here;


That’s the lower CL of the assumed CV of 35% – going up with increasing n. Or:
    n   CLlo    CLhi
—————————————————————
   10  29.78%  46.18%
   12  30.13%  44.66%
   14  30.41%  43.59%
   20  31.02%  41.67%
   50  32.29%  38.72%
  100  33.01%  37.49%
 1000  34.33%  35.72%
10000  34.78%  35.22%

Haven’t tried . :-D


P.S.: You have mail.

Scientists often have a naïve faith that
if only they could discover enough facts about a problem,
these facts would somehow arrange themselves
in a compelling and true solution.    Theodosius Dobzhansky
