Variance Conversion Calculator

The variance calculator finds the variance of a set of numbers. It is a measure of how tightly clustered the data is around the mean.

A discrete random variable has a countable number of possible values. The probability of each value of a discrete random variable is between 0 and 1, and the sum of all the probabilities is equal to 1. A continuous random variable takes on all the values in some interval of numbers.
