How to calculate multimode in Python?

Mode represents the single most frequent value in a list, while multimode provides a list of all the values that occur with the highest frequency.

Let’s see how to calculate multimode in Python.

Multimode Calculation Using the statistics Module

To calculate multimode, we need to import the statistics module.

Fortunately, the statistics module provides a dedicated function for calculating multimode.

import statistics as s

x = [1, 5, 7, 5, 43, 43, 8, 43, 6]

multimode = s.multimode(x)
print("Multimode equals: " + str(multimode))

multimode python

In this example the list x contains several numbers, with 43 appearing most frequently (three times). The multimode function returns a list containing 43, which is the value with the highest frequency.

Understanding the Difference Between Mode and Multimode

The mode is the most frequent number in a list of numbers.
The multimode is a list of the most frequent numbers in a list of numbers.

For example, if a list of numbers is [1, 2, 3, 3, 4, 4], then the mode would be either 3 or 4, and the multimode would be [3, 4], assuming both values appear with the highest frequency.

The difference between mode and multimode is that mode is a single number, while multimode is a list of numbers. While mode provides a quick snapshot of the most frequent value, multimode offers a more detailed view, especially in datasets where multiple values occur with the same highest frequency.
