Population Variance Calculator
Calculate population variance, population standard deviation, mean, and dataset size from a list of values.
Enter values separated by commas, spaces, or line breaks.
Formula:

How it works
Population variance assumes the data represents the entire population, so the sum of squared deviations is divided by N.
Examples
- 12, 15, 18, 21, 24
- Mean, variance, and standard deviation are all calculated from the same dataset.
FAQ
- What is population variance?
Population variance measures how far values in an entire population are spread around the population mean.
- What formula does this calculator use?
It uses population variance: σ² = Σ(x − μ)² / N.
- How should I enter the data?
Enter values separated by commas, spaces, or line breaks.
- What is the difference between population and sample variance?
Population variance divides by N, while sample variance divides by n − 1.
