The Variance in Gambling

The concept of the variance in gambling comes from mathematics. Strictly speaking, this science is called the dispersion measure of the deviation values ​​of some value from the mean, or expectation.

In the same games of chance variance is a measure of deviation of actual results from the game of expectations that is actually the same thing. This concept is at the top of any game. Manifests itself in the form of a dispersion of random sequences of wins and losses. In general, the excitement of their existence and prosperity must only variance. After all, if everyone obeyed strictly mathematical calculations, the casino simply would not have arisen, and as a result, and there would be no excitement in these games, and in general gambling also would not be. Keep in mind that the larger the variance of the game, the greater the initial bank to have. This is to ensure that the losing streak would survive if it started with the first of your bet.

In general, the variance is not a negative or a positive factor gambling. It is an advantage for those players whose expectation was negative. In this case, the player can only rely on the variance, but it will help him win. Often we see that the way it really is. But sometimes the variance is negative and play. For example, betting on anything, the player often convinced that it must necessarily be correct, otherwise even that cannot be. But the concept of dispersion is different.

Consider the case of a conventional tape measure. If the numbers are very often alternating the colors, we can say that the variance in color in roulette is very small. But the frequent cases where the same color falls more than ten or even fifteen times in a row, are especially prone to such cases of online casinos. Here you can talk about a very high level of dispersion.

In particular cases, the variance can be considered in relation to each game separately. But in general, the variance - is a fundamental factor in the existence of unpredictability game.
