- 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}}.
