In mathematics, particularly in the field of statistics, the mode is the value that occurs most often in a series of numbers. It is also referred to as the modal value. If a set of data values does not have a repeating number, then it has no mode.
The mode is a type of average that is used to gather information about a sample population of observed values, which is usually a list of numbers. A list is said to be bimodal if it contains two modes and multimodal if it has several modes. Other types of averages in statistics are the mean and median.
