Quick Summary

In mathematics, the mode is one of the three main ways to describe the average value of a list of numbers. It represents the value that appears most frequently in a dataset. For example, in the list of numbers 2, 3, 3, 4, 5, the mode is 3 because it occurs twice, more than any other number.1

The mode is a measure of central tendency, alongside the mean (the sum of values divided by the count of values) and the median (the middle value in an ordered list). The mode is particularly useful for categorical data or when identifying the most common occurrence is important.123
