- 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, 1})yields 10.98
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.
