SampleSD( <List of Numbers> )
Returns sample standard deviation of given list of numbers.
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.
SampleSD[{1, 2, 3, 4, 4},{1, 1, 1, 2}] yields 1.08.

Note Hint: If the list contains undefined variables in the Menu view cas.svg CAS View, the command yields a formula for the sample standard deviation.
SampleSD[{1, 2, a}] yields \frac{\sqrt{a²-3a+3}}{\sqrt{3}}.
