- Median[ <List of Raw Data> ]
- Determines the median of the list elements.
- Examples:
Median[{1, 2, 3}]
yields 2.Median[{1, 1, 8, 8}]
yields 4.5.
- Median[ <List of Numbers>, <List of Frequencies> ]
- Calculates the weighted median of the list elements.
- Example:
Median[{1, 2, 3}, {4, 1, 3}]
yields 1.5.Median[{1, 2, 3}, {4, 1, 6}]
yields 3.
CAS Syntax
- Median[ <List of Numbers> ]
- Determines the median of the list elements.
- Examples:
Median[{1, 2, 3}]
yields 2.Median[{1, 1, 8, 8}]
yields the numeric value 4.5 or its evaluation $\frac{9}{2}$
Note:
- If the length of the given list is even, the arithmetic mean of the two center elements is returned.
- See also Mean command.
