The Population Variance Calculator is used to calculate the population variance of a set of numbers.

FAQ

Population variance (σ^{2}) indicates how data points in a given population are distributed. This is the average of the distances from each data point in the population to the mean square.

The population variance of a finite population of size N is calculated by following formula:

Where: σ^{2} = population variance x_{1}, ..., x_{N} = the population data set μ = mean of the population data set N = size of the population data set
