WebSep 17, 2020 · The standard deviation is the average amount of variability in your dataset. It tells you, on average, how far each value lies from the mean. A high standard deviation means that values are generally far from the mean, while a low standard deviation indicates that values are clustered close to the mean.

Web. Population 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.
