WebStandard deviation for a normal distribution. The normal distribution leads to the least conservative estimate of uncertainty; i.e., it gives the smallest standard deviation. The calculation of the standard deviation is based on the assumption that the end-points, ± a, encompass 99.7 percent of the distribution. Degrees of freedom. WebThe population standard deviation formula is given as: σ = 1 N ∑ i = 1 N ( X i − μ) 2 Here, σ = Population standard deviation N = Number of observations in population Xi = ith observation in the population μ = Population mean Similarly, the sample standard deviation formula is: s = 1 n − 1 ∑ i = 1 n ( x i − x ―) 2 Here,
