WEBPopulation standard deviation: σ = ∑ ( x i − μ) 2 N. Sample standard deviation: s x = ∑ ( x i − x ¯) 2 n − 1. The steps in each formula are all the same except for one—we divide by one less than the number of data points when dealing with sample data. We'll go through each formula step by step in the examples below.

WEBFeb 12, 2020 · Work through each of the steps to find the standard deviation. Calculate the mean of your data set. The mean of the data is (1+2+2+4+6)/5 = 15/5 = 3. Subtract the mean from each of the data values and list the differences. Subtract 3 from each of the values 1, 2, 2, 4, 6. 1-3 = -2.
