Improve your poker game with this in-depth standard deviation in poker guide. Proven tactics and analysis from professional grinders.
## Standard Deviation and Variance in Poker
Standard deviation measures how much your results fluctuate around your average win rate. In NLH cash games, a typical standard deviation is 60-80bb/100. In PLO, it is 100-140bb/100. In tournaments, variance is even higher.
What this means practically: with an 80bb/100 standard deviation and 3bb/100 win rate, you will have losing sessions regularly. Over 1,000 hands, your result could range from -157bb to +163bb (within one standard deviation).
Understanding variance helps you emotionally cope with losing streaks and make better bankroll management decisions. Variance is not bad luck — it is a mathematical certainty. Proper bankroll management ensures you survive the inevitable swings.
## Applying This at the Tables
Understanding standard deviation and variance in poker is one thing — executing it under pressure is another. Practice by focusing on this specific concept for an entire session, then review relevant hands afterward to evaluate your execution.
