Dispersion Measurement
Variance measures how far a set of numbers are spread out from their average value. It is a fundamental tool in statistics for understanding data volatility and consistency.
Sample vs Population
Our tool calculates both sample variance (using n-1) and population variance (using n), giving you the flexibility to analyze entire datasets or representative subsets.
