What is Variance?

Variance measures how far each number in a set is from the mean. It is the square of standard deviation and represents the dispersion of data points around the mean. Variance is used in risk assessment, portfolio theory, quality control, and statistical analysis. Sample variance (using n-1) provides an unbiased estimate when working with a sample of a larger population.

How to use

Enter your dataset values separated by commas, spaces, or new lines. Select whether your data is a sample or population. The calculator displays variance, standard deviation, sum of squares, degrees of freedom, and provides interpretation of the variance level (low, moderate, high, or very high).
