Reply #7: too few to conclude anything: way way too small a sample size

[oscar111]

do any science experiment and you will find two groups vary from each other

JUST BY CHANCE

quite a lot , with small tiny group sizes.

as groups get larger, chance variance equals out and the chosen variable.. race.. starts to have a detectable effect.

your effort is laudable, but dont draw any conclusions from a tiny teeny no. of trials.

example was how antioxidants in small trials seemed to cure everything, ten yrs ago. Larger trials later, and they cure almost nothing.. perhaps three things. Cooper was the sincere error guy, getting the public excited on this .
