- 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> ]
- Calculates the standard deviation of the numbers in the list.
- Example:
SD[{1, 2, 3, 4, 5}]yields \sqrt{2}.SD[{-3 + 2 x, -1- 4 x, -2 + 5 x^2}]is evaluated as
\sqrt{2} \frac{\sqrt{25x⁴ + 10x³ + 28x² - 18x + 3} \ } { \ 3 \ }.
- Note:See also Mean Command.
