Splet19. sep. 2024 · To calculate the variance in a dataset, we first need to find the difference between each individual value and the mean. The variance is the average of the squares of those differences. We can express the variance with the following math expression: σ2 = 1 n n−1 ∑ i=0 (xi − μ)2 σ 2 = 1 n ∑ i = 0 n − 1 ( x i − μ) 2.
