The population variance is the variance of the population. To calculate the population variance, use the formula σ2=1NN∑i=1(xi−μ)2 σ 2 = 1 N ∑ i = 1 N ( x i − μ ) 2 where N is the size of the population consisting of x1,x2,…
1 авг. 2024 г. · The formula to calculate population variance is: σ^2 =\dfrac{ Σ (x_i – μ)^2} N · where: Σ: A symbol that means “sum”; μ: Population mean; x_i : ... |
Population variance tells us how data points are spread out. It's the average of the distance from each data point to the mean, squared. |
