Mean, Median and Mode Calculator

Use this mean, median and mode calculator to work out three common measures of central tendency instantly. Enter a list of numbers separated by commas, spaces or line breaks to calculate the mean, median and mode, along with the count, sum, minimum and maximum values.

This calculator is useful for maths homework, statistics practice, data analysis and quick number checks.

What are mean, median and mode?

Mean, median and mode are three different ways of describing the centre of a set of numbers.

Mean

The mean is what most people call the average. It is found by adding all the numbers together and dividing by how many numbers there are.

Median

The median is the middle number when the values are arranged in order. If there is an even number of values, the median is the average of the two middle numbers.

Mode

The mode is the number that appears most often in the list. Some sets have one mode, more than one mode, or no mode at all.

Formulas for mean, median and mode

Mean formula

Mean = Sum of all values ÷ Number of values

Median method

1. Put the values in order from smallest to largest.
2. Find the middle value.
3. If there are two middle values, average them.

Mode method

Find the value or values that occur most frequently.

Examples of mean, median and mode

Example 1: One clear mode

Numbers:
2, 4, 4, 6, 8

• Mean = (2 + 4 + 4 + 6 + 8) ÷ 5 = 4.8
• Median = 4
• Mode = 4

Example 2: Even number of values

Numbers:
1, 3, 5, 7

• Mean = 4
• Median = (3 + 5) ÷ 2 = 4
• Mode = No mode

Example 3: More than one mode

Numbers:
1, 2, 2, 3, 3, 4

• Mean = 2.5
• Median = 2.5
• Mode = 2 and 3

Mean vs median vs mode

These measures can give different results depending on the data.

• Mean uses every value in the set
• Median focuses on the middle value
• Mode looks for the most common value

For skewed data or data with outliers, the median can sometimes be more useful than the mean.

When to use mean, median or mode

Use the mean when:

• you want the arithmetic average
• all values should influence the result
• the data is fairly balanced

Use the median when:

• you want the middle point
• the data includes outliers
• you want a value less affected by extremes

Use the mode when:

• you want the most common value
• you are analysing repeated outcomes
• you are working with frequency-based data

Why mean, median and mode matter

These three measures are widely used in:

• school and college maths
• statistics
• business reporting
• survey analysis
• test score analysis
• data summaries

They help you understand a dataset quickly without reviewing every individual value in detail.

Frequently asked questions

How do you calculate mean, median and mode?

Mean is the total divided by the count, median is the middle value in order, and mode is the most frequently occurring value.

Can there be more than one mode?

Yes. A dataset can have two or more modes if multiple values appear the same highest number of times.

Can a set of numbers have no mode?

Yes. If every value appears only once, there is no mode.

What is the difference between mean and average?

In most everyday use, average usually refers to the arithmetic mean.

Is median always one of the numbers in the list?

Not always. If there is an even number of values, the median can be the average of the two middle numbers.

Can I enter decimals and negative numbers?

Yes. This calculator works with whole numbers, decimals and negative values.
