In poker, variance explains the natural fluctuations in a player’s results, regardless of their skill level. It accounts for winning or losing streaks that may not reflect the player’s true skill or strategy. Variance is an inherent part of poker because, while skill determines long-term success, short-term results are often influenced by chance.
Variance Example
For example, a skilled player may make the right decisions in a game but still lose multiple hands in a row due to variance, as the cards do not fall in their favor temporarily.
