Mean, Median & Mode Calculator

A fast, free online tool.

Fast, free and designed to work beautifully on any device.

Use this Mean, Median & Mode Calculator to find the three main measures of central tendency for a set of numbers.

Enter your values to calculate the mean, median, mode, total, and number of values. This tool is useful for schoolwork, surveys, scores, business data, research, and everyday number comparisons.

How to use the Mean, Median & Mode Calculator

  1. Enter your numbers in the values box.
  2. Separate each number with a comma, space, tab, or new line.
  3. Select Calculate.
  4. Review the mean, median, mode, total, and number of values.

For example, you can enter:

12, 18, 22, 22, 25, 26, 30

Mean median and mode example

Suppose you have the following values:

4, 6, 6, 8, 10, 10, 10, 12

The calculator gives these results:

Each result describes the data in a different way.

What is the mean

The mean is the arithmetic average of a set of values.

To find the mean, add all values together and divide the total by the number of values.

Mean = Total of all values / Number of values

For the values 4, 6, 6, 8, 10, 10, 10, 12:

Total = 66
Number of values = 8

66 / 8 = 8.25

The mean is 8.25.

The mean can be useful when the values are fairly balanced. It can be affected by unusually high or low values, also called outliers.

What is the median

The median is the middle value after the numbers are arranged from smallest to largest.

If there is an odd number of values, the median is the one number in the middle.

If there is an even number of values, the median is the average of the two middle numbers.

For the values 4, 6, 6, 8, 10, 10, 10, 12, there are eight values. The two middle values are 8 and 10.

8 + 10 = 18
18 / 2 = 9

The median is 9.

The median can be especially useful when one or two extreme values would distort the average.

What is the mode

The mode is the value that appears most often in a data set.

For the values 4, 6, 6, 8, 10, 10, 10, 12, the number 10 appears three times.

The mode is 10.

A data set can have:

For example, the values 3, 3, 5, 5, 7 have two modes: 3 and 5.

When to use mean median or mode

Use the mean when you need the overall average and the data does not include major outliers.

Use the median when you need the middle value and want to reduce the effect of unusually high or low numbers.

Use the mode when you need to identify the most common value, choice, score, size, or category.

Comparing all three can give a clearer picture of your data than using only one result.

Frequently asked questions

Can a dataset have more than one mode?

Yes. If two or more values tie for the highest frequency, the set is bimodal (two modes) or
multimodal (several modes) for example, in 3, 3, 5, 5, 7, both 3 and 5 are modes. The calculator
lists every mode it finds, so you won’t miss a tie.

What does it mean when there is no mode?

It means every value appears equally often for example 4, 7, 12, 19. There’s nothing wrong with
your data; “no mode” is a valid, correct answer. It usually tells you the values are spread out with
no clear favorite, so the mean or median may be the better summary for that dataset.

Why are my mean, median, and mode different numbers?

Because your data is skewed stretched out more on one side. When a few large or small values pull
the average away from the middle, the mean drifts while the median stays put. Try the worked example
above: one very large number added to the list would change the mean a lot, the median only a little,
and the mode not at all. If all three are close together, your data is nicely balanced.

Which average should I use in my school assignment?

State all three if you can teachers like seeing you compare them. If you must pick one:
use the mean for the classic “find the average” question, the median when the question mentions
outliers or “typical” value, and the mode when it asks for the most common score, size, or choice.
Our guide “Median Average Calculator: A Complete Guide to Mean, Median, and Mode” walks
through worked examples for each.

Does this calculator save or store my numbers?

No. Like every tool on ToolsByMeh, it runs entirely in your browser your numbers are never sent to a
server, stored, or tied to an account. There are no sign-ups and no tracking of your inputs. Refresh
the page and your entries are gone.

How many numbers can I enter?

There’s no practical limit paste in a full class of test scores or a long survey column and the
calculator handles it. Just keep one value per separator (comma, space, tab, or new line) and
double-check for typos, since one mistyped value changes all three results.

Important notes

This calculator works with positive numbers, negative numbers, and decimals.

Make sure every value is entered correctly. One missing number or typing error can change the result.

Mean, median, and mode describe the centre or most common part of a data set. They do not explain every detail about the data, such as how spread out the values are or whether there are unusual patterns.

Use the Percentage Calculator to compare part of a total, or the Unit Converter to convert measurements before calculating statistics.
