So over larger sample sizes variance has less affect.
Let's step back a bit. I accept that I was a bit direct a few posts back - you said patronizing. I'm not sure exactly what you thought was patronizing, but I do apologize for whatever tone I used that has made this conversation nearly impossible.
I'm being perfectly straightforward with you about a subject that can be readily verified with a 10-second web search. I understand that it's a rather advanced mathematical concept, which is why I'm willing to take the time to explain it to you.
Let's make sure we're on the same page and talking about one topic at a time.
What's your definition of variance?
