Default Re: Hold \'Em Standard Deviation.

isn't this a population proportion where p=.75?

I believe the formula for standard deviation is sqrt(p*(1-p)/n)

So if you run it 2 times, SD is 0.31. Losing twice seems more than 2 SDs away. But the SD will change depending on the number of trials.

PS, I don't think SD in the above example is very useful because this distribution is not normal, so you need N to be at least 30 before SD becomes a reasonable estimate.
