What Is the Mode of a Set of Numbers?

The mode of a set of numbers is the value which occurs the most often in the set. For example, the mode of {1, 2, 3, 2, 4} is 2, since it occurs twice.

The easiest method of calculating the mode is to put all of the numbers in the set in numerical order and then count which number occurs the most times. It is possible to have more than one mode if multiple numbers in a set occur the same number of times. There are special terms for having two modes (bimodal) and having more than two modes (multimodal).
