webSep 19, 2023 · The formula for variance for a sample set of data is: Variance = s2 = Σ(xi −x¯¯¯)2 n − 1 s 2 = Σ ( x i − x ¯) 2 n − 1. Take the square root of the population variance to get the standard deviation. Population standard deviation = σ2−−√ σ 2. Take the square root of the sample variance to get the standard deviation.
