- 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}.
- Note:See also Mean Command.
