SampleSD( <List of Numbers> )
Returns the sample standard deviation of given list of numbers.
Example: SampleSD({1, 2, 3}) yields 1.
Example: stdev({1, 2, 3}) yields 1.


SampleSD( <List of Numbers>, <List of Frequencies> )
Returns the sample standard deviation of the numbers having the given frequencies.
Example: 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.
Example: SampleSD({1, 2, a}) yields \frac{\sqrt{a²-3a+3}}{\sqrt{3}}.
