Population Variance Calculator
Calculate population variance by dividing squared deviations by the number of observations.
About this tool
Calculate population variance by dividing squared deviations by the number of observations. Enter the measurements or values in the labeled fields. The calculation runs locally in your browser without uploading input. Units are carried through from your inputs, so use consistent units and check that the formula assumptions match your situation. For practical work, independently confirm the entered values, output precision, and relevant unit conventions before relying on this estimate.
How to use this tool
- Enter values in the labeled fields.
- Use consistent measurement units where applicable.
- Calculate and check the result against your use case.
