- Mean[ <List of Raw Data> ]
- Calculates the arithmetic mean of list elements.
- Example:
Mean[{1, 2, 3, 2, 4, 1, 3, 2}]
yields a = 2.25 andMean[{1, 3, 5, 9, 13}]
yields a = 6.2.
- Mean[ <List of Numbers>, <List of Frequencies> ]
- Calculates the weighted mean of the list elements.
- Example:
Mean[{1, 2, 3, 4}, {6, 1, 3, 6}]
yields a = 2.56 andMean[{1, 2, 3, 4}, {1, 1, 3, 6}]
yields a = 3.27.
CAS Syntax
- Mean[ <List of Numbers> ]
- Calculates the arithmetic mean of the list elements.
- Example:
Mean[{1, 2, 3, 5, 44}]
yields a = 11.
- Mean[ <List of Numbers>, <List of Frequencies> ]
- Calculates the weighted mean of the list elements.
- Example:
Mean[{1, 2, 3, 4}, {6, 1, 3, 6}]
yields a = 2.56 andMean[{1, 2, 3, 4}, {1, 1, 3, 6}]
yields a = 3.27.
