A Variance calculator (σ2) is a measure of the difference between the numbers in a data set.
In probability and statistics, the variance is the squared deviation of a random variable from its mean.
The variance is the square of the standard deviation, the second central moment of a distribution, and the covariance of the random variable with itself.
Steps to perform the calculation:
1: Enter the numbers separated by a comma in the respective input field
2: Click the button “Calculate Variance” to get the result
3:The variance for the given set of data will be displayed
