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.

WEBThe population standard deviation is a measure of how much variation there is among individual data points in a population. It's a way of quantifying how spread out the data is from its mean. A small standard deviation means that the data points are generally close to the mean, while a large standard deviation means that the data is more dispersed.
