Enter numbers separated by commas or spaces (e.g., 1, 2, 3, 4, 5)
Our Variance Calculator helps you measure the spread or dispersion of your data. Variance and standard deviation are fundamental measures in statistics that tell us how much the data points deviate from the mean.
The average of the squared differences from the mean. It measures how far the data points are spread out.
Formula: σ² = Σ(xᵢ - μ)² / n
The square root of variance. It's in the same units as the original data and is easier to interpret.
Formula: σ = √σ²
