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 \frac{\sqrt{a²3a+3}}{\sqrt{3}}.
Following text is about a feature that is supported only in GeoGebra 4.2.
