- SampleSD[List of Numbers]
- Returns sample standard deviation of given list of numbers.

**Example:**

`SampleSD[{1,2,3}]`

yields *1*.

## CAS Syntax

- SampleSD[List of Numbers]
- Returns sample standard deviation of given list of numbers. If the list contains undefined variables, it yields a formula for the sample standard deviation.

**Example:**

`SampleSD[{1,2,a}]`

yields *sqrt(a²-3a+3)/sqrt(3)*.
