Definition of Mode

Today we will discuss the definition of Mode. Mode is a term that is used any time we have a group of numbers.

Mode is the number in a given set of numbers that occurs with the greatest frequency (or most often). A good way to remember this is to always think:

MOde happens MOst often

When will you deal with mode? Mode will be used as a way to try and describe any set or group of numbers. This can be in statistics, histograms, or line plots. Any time you have a group of numbers you can find the mode.

Example of Mode

Let’s look at an example. For the numbers: 15, 10, 19, 19, 7, 11, 15, 19, 20, 12, 17, and 18, find the mode. We see that the number 19 occurs 3 times, so it is the mode of the data set. The number 15 occurs twice, and all other numbers only occur once. Note that the numbers do not have to be in any order to find the mode. It might help, but isn’t necessary.

In Review:

Always remember the mode is the number that shows up most often (greatest frequency) in a set of numbers.
