What is Mode?

In statistics, the mode is the most commonly occurring value in a numerical set of data. The mode is the number that occurs most often or is repeated the most.

The mode is one of the observations of data used in summary statistics, and is used to describe the central tendency of the data.

The mode of a data set is the most commonly occurring value that occurs at least two times. Thus, it is possible for a data set to have no mode at all if there are no numbers that repeat.

It is also possible for a data set to have more than one mode if multiple values occur the same number of times. This is referred to as a multimodal dataset.

How to Find the Mode

You can find the mode by counting the number of times each value in a set of numbers is repeated. The number that is repeated the most is the mode.

Remember that multiple numbers might be repeated the same number of times, although it’s not common. If multiple numbers are repeated the same number of times as the most commonly repeated number they are also part of the mode.

You’ll also recall that some datasets have no mode at all. If no numbers are repeated at all then there is no mode.

Steps to Find the Mode

  1. Step 1: count the occurrences of each number in the set
  2. Step 2: find the number or numbers that occur the most
  3. Step 3: that’s it, you found the mode!

Examples of Calculating the Mode

Calculate the mode of the following numbers: [3,7,5,7,6,7,3]

Step 1: count the occurrences of each number.

Value: Frequency
3 2
5 1
6 1
7 3

Step 2: find the number or numbers that occur the most.
7 occurs the most in this set.

Thus, the mode of the numbers above is 7.

Calculate the mode of the following numbers: [2,6,5,2,6,6,2,4]

Step 1: count the occurrences of each number.

Value: Frequency
2 3
4 1
5 1
6 3

Step 2: find the number or numbers that occur the most.
2 and 6 occur the most in this set.

Thus, the dataset is multimodal and the mode of the numbers above is 2 and 6.

The mode is the least used statistical observation, since mean and median are most commonly used. Try our mean or median calculators.
