Mean and Median Calculator

Use this free calculator to find the mean, median, mode and range of a list of numbers. Enter marks, scores, measurements or other values to see a clear statistical summary.

It is useful for students, teachers, researchers and anyone who needs to understand the average and spread of a set of values.

How to use the Mean and Median Calculator

  1. Enter or paste the numbers into the input box.
  2. Separate each value with a comma, space or new line.
  3. Calculate the result.
  4. Review the mean, median, mode and range.

For example, enter: 5, 8, 8, 10, 14.

The calculator will show the average value, the middle value, the most frequent value and the difference between the highest and lowest values.

What do mean, median, mode and range mean?

Mean is the average. Add all values together and divide by the number of values.

Median is the middle value after the numbers are arranged from lowest to highest.

Mode is the value that appears most often.

Range is the difference between the highest and lowest values.

These measures can give different information about the same list of numbers.

Example

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

  • Mean = 8
  • Median = 8
  • Range = 8

The mean and median are the same in this example because the values are evenly spread around the centre.

FAQs

What is the difference between mean and median?

Mean is the average of all values. Median is the middle value once the numbers are ordered.

What happens if there are two middle numbers?

The calculator finds the average of the two middle values to calculate the median.

Can there be more than one mode?

Yes. A list can have more than one value that appears most often. Some lists have no mode if every value appears only once.

Can I use this for test marks?

Yes. Teachers and students can use it to analyse marks, quiz scores and other results.

Is this the same as standard deviation?

No. Mean and median describe the centre of the data. Standard deviation shows how widely values are spread around the mean.
