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[ <List of Numbers>, <List of Frequencies> ]
Calculates the weighted standard deviation of the given numbers.
Example: SD[{-3 + 2 x, -1- 4 x, -2 + 5 x^2}] is evaluated as $\frac{\sqrt{25x⁴ + 10x³ + 28x² - 18x + 3} \; \sqrt{2} } { \; 3 \; }$
