Re: Are Winrates Normally Distributed?

Nice work Max, thanks a lot.

So if I play 20,000 hands and my BB/100 is 1.5, I know that the sampling distribution for samples of that size is normally distributed.

Don't the numbers you posted indicate that this is not the case? Sampling distributions are going to approximate normal with n sufficiently large. What your numbers seem to show is that n=100 is not large enough.
Correct me if I'm wrong, but you've shown that the sampling distribution for bb/100 is decidedly not normal. What I want to know is how does this affect confidence intervals?

There is no such thing as sampling distribution for BB/100 (the measure), only a sampling distribution for samples of size X (in this case, 100). If I did the same analysis using BB/hand or BB/1000 or bb/21, I would find the exact same results.
