StandardDeviation

StandardDeviation[data] gives the sample standard deviation estimate of the elements in data. StandardDeviation[dist] gives the standard deviation of the distribution dist.

Examples

Compute standard deviation of a list:

StandardDeviation[{1, 2, 3, 4, 5}]
(* Sqrt[5/2] *)

(* Standard deviation of a distribution *)
StandardDeviation[NormalDistribution[0, 2]]
(* 2 *)
