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