SampleSD[ <List of Numbers> ]
Returns sample standard deviation of given list of numbers.
Example:
SampleSD[{1, 2, 3}] yields 1.


SampleSD[ <List of Numbers>, <List of Frequencies> ]
Returns the standard deviation of the sample of numbers having the given frequencies.
Example:
SampleSD[{1, 2, 3, 4, 4},{1, 1, 1, 2}] yields 1.08.


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{a²-3a+3}}{\sqrt{3}}.
