- SampleSD( <List of Numbers> )
- Returns 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 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}}.
