SampleSD Command

SampleSD( <List of Numbers> )

Returns the sample standard deviation of given list of numbers.

SampleSD({1, 2, 3}) yields 1.

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.

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.

SampleSD({1, 2, a}) yields \(\frac{\sqrt{a²-3a+3}}\{\sqrt{3}}\).
