Population variance
Population variance measures the average squared distance of every value from the population mean.
Population vs sample
Population variance divides by N. Sample variance estimates a larger population and divides by n − 1.
Interpreting results
A smaller variance means values are clustered near the mean, while a larger variance indicates greater spread.
Frequently asked questions
What is the population variance formula?
Subtract the population mean from each value, square every difference, add the squares, and divide by the total number of values.
Can I paste values on separate lines?
Yes. The calculator accepts commas, spaces, semicolons, tabs, and line breaks.
Does this calculator use N or N − 1?
It uses N because this calculator is specifically designed for population variance.
