Written by:

Below is a mode calculator, which will compute a mode from a list of numbers. Enter any type of number including decimals or negative, separated with any non-number and the tool will return the list's mode.

What is the Mode of a Set of Numbers?

The mode of a set of numbers is the number that occurs most often in the set.

It is one of the big three ways to describe the central tendency of a set of numbers, along with arithmetic average (the sum of the numbers divided by the number of numbers) and median (the number in the middle of an ordered set of numbers).

Finding a Mode in a Set

Finding the mode is as simple as counting how many times each number in a set occurs, then crowning the top value as the mode. If there are more than one value with the same count at the top, you can call the set bimodal (or trimodal, etc.) – this calculator will compute this for you.

Some sets will have no mode – to find the tendency, you can either use a different measure (such as average), or "bucket" the numbers to create a histogram.

Note that, especially for histograms, it's common to use "bimodal" to describe a set even if the number of values doesn't exactly match. You often see this with salaries – for example, first year law graduates see two "peaks" of rough compensation in the United States and the income is often described as bimodal.

Using the Mode Calculator

In the text box, enter a set of numbers to find the mode. When satisfied, hit the Compute Mode button and we'll report the mode.

This calculator is very forgiving of inputs. Enter your numbers in (almost) any way you choose – as long as you space the numbers apart somehow we should be able to pick them out. Try tabs, commas, spaces, new lines, etc.

To verify we understood your input, look how many values we found in the Number of Values Input.
