- Median[ <List of Numbers> ]
- 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.
- Note:If the length of the given list is even, the arithmetic mean of the two center elements is returned.
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 
$\frac{9}{2}$
- Median[ <List of Numbers>, <List of Frequencies> ]
- Calculates the weighted median of the list elements.
- Example:
Median[{1, 2, 3, 4}, {4, 1, 4, 9}]yields 3.5.
- Note: If the length of the given list is even, the arithmetic mean of the two center elements is returned.
