- 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*and`Mean[{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*and`Mean[{1, 2, 3, 4}, {1, 1, 3, 6}]`

yields*a = 3.27*.
