The calculator above computes population standard deviation and sample standard deviation, as well as confidence interval approximations. Population Standard Deviation The population standard deviation, the standard definition of σ, is used when an entire population can be measured, and is the square root of the variance of a given data set.

The standard deviation is equal to the square root of variance. Where, σ = Standard Deviation ∑ = Sum of each Xi = Data points μ = Mean N = Number of data points So, now you are aware of the formula and its components. Let's do …
