Standard Deviation
A statistical measure of the spread of your results around your average win rate. In poker, standard deviation is typically measured in big blinds per 100 hands (bb/100). A typical standard deviation for No-Limit Hold'em is 60-100 bb/100, meaning significant swings are normal even for winning players.
Example
Your standard deviation is 80bb/100 over 50,000 hands. This means roughly 68% of your results will fall within one standard deviation of your true win rate.
