Re: Standard Deviation Question, How to do it?
Standard variance doesn't sound right. There's standard deviation, which is the square root of variance. I'm not trying to pick on your terminology or make you feel stupid, I just want to make sure I know what you want. If you don't know the technical term, just tell us what you want to do with the number.
The other question is what data you have. Profit and loss per session? Per hand? Something else?
