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.

Hint: If the list contains undefined variables in the

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}}.
