A question for a math head (how you doing FirePhil ;o))

I have a Standard Deviation/100 hands of 42.2 Big Bets.

WTF does this mean to me?

Standard deviation is the square root of the variance.

[PokerWoody]

Standard deviation is the square root of the variance.

But what does it mean too me? I mean, what should I think about this statistic? does it even mean anything or is it just there to keep the math boys all hard and stuff?

[Dice Man]

I dunno. I can't see as what it would mean to have a variance of 2000 BBs. Or maybe it means variance per 10000 hands of 2000 BBs.Variance is something like the average distance from the average (if that makes sense), so maybe this number represents how crazy your play is. The bigger it is the more likely you are to rake big pots and lose big pots. The smaller it is the more likely you are to keep the pots small win or lose.

Sample standard deviation / (square root of sample size) = E.S.E


As the size of any given chip stack is a continous variable as opposed to a binary variable then the parameter is the chip stack itself and the estimator is the sample mean of the chip stack during any number of sessions.

I know this is just an estimator and poker tracker is probably exact in its calculations but this is just a formula for a pretty good estimate.

p.s E.S.E is the estimated standard error in the calculations. So usually your range will be the sample mean + - (2x E.S.E).

This is a good way of determining how much u r making in each session, especially if your buy in is the same every time.

e.g ($115,$135) would mean u r averaging between 15 and 35 profit a session at NL100 if you were buying in for $100, with the mean value being $125.

Doesn't that mean you will on average make (winrate) +/-42.2BBs per 100 hands?

Does that make me awesome?

I've decided, like everything else I don't really understand, to just ignore it...deviation does sound cool though. I like the idea of being a deviater.

Actually I did check up and an average standard deviation stat for winning players is like 43/100 so I guess i'm just an average. What's yours? I reckons yours is gonna be the big numberz!
