Ring,

Your extremely insulting. "read the thread". [censored] off. Go talk down to an 8 year old something.

Rain,

I see the difference now. You made the assumption that in every example there is either a yes/no response. Either a win or a loss. My problem with this reasoning is the following data set:

0 0 0 0 0 0 1

From your logic, it seems like the standard deviation is 0.25. Your logic also seems to point that the mean would be 0.5. Either you win or you don't. When clearly this is not the case. I guess you reasoned that because they have the same means, they have the same standard deviations. This isn't the case though. Two data sets can have two completely different standard deviations but similar means.
