(definition)

**Definition:**
The value that occurs most often. If no value is repeated, there is no mode. If more than one value occurs with the same greatest frequency, each value is a mode.

**See also**
*median*, *mean*, *midrange*.

*Note:
The mode of 1, 1, 3, 50, and 60 is 1 since it occurs twice and all the other values occur once. The set {1, 1, 2, 3, 3, 4} has two modes, 1 and 3, and is called bimodal. If there are more than two modes, it is multimodal.*
