# Mode

In statistics, the mode of a set of data is the one that occurs most. It is the value x at which its probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled. A mode of a continuous probability distribution is often considered to be any value x at which its probability density function has a locally maximum value, so any peak is a mode.

The mode of a sample is the element that occurs most often in the collection.

For Example: the mode of the sample

[1, 3, 5, 5, 5, 5, 7, 7, 12, 12, 17] is 5.

Unlike the median and the mean, the mode is not necessarily unique. There might be several different values that occur the same number of times.

## Bi Modal and Multimodal

Given the list of data [1, 1, 2, 4, 4] the mode is not unique – the dataset may be said to be bimodal, while a set with more than two modes may be described as multimodal.
