VARIANCE
Variance
In probability theory and statistics, variance measures how far a set of numbers is spread out. A non-zero variance is always positive: A small variance indicates that the data points tend to be very close to the mean and hence to each other, while a high variance indicates that the data points are very spread out from the mean and from each other.The above text is a snippet from Wikipedia: Variance
