SD[ <List of Numbers> ]
Calculates the standard deviation of the numbers in the list.
Example:
SD[{1, 2, 3, 4, 5}] yields 1,41.
SD[ <List of Numbers>, <List of Frequencies> ]
Calculates the weighted standard deviation of the given numbers.
Example:
SD[{20, 40, 41, 42, 40, 54}, {20, 6, 4, 5, 2} ] yields 5.96.

CAS Syntax

SD[ <List of Numbers> ]
SD[ <List of Numbers>, <List of Frequencies> ]
Example:
SD[{1, 2, 3, 4, 5}] yields \sqrt{2}.
