How to use this calculator

  1. Type or paste your numbers in the box.
  2. Separate them with commas, spaces or line breaks.
  3. Read the mean at the top and the other statistics below it.
  4. Copy the result or share a link with the same list.

The formula

Mean = Sum ÷ Count. Median = the middle value of the sorted list (or the average of the two middle values when the count is even). Mode = the most frequent value. Range = Largest − Smallest.

Worked example

For 12, 18, 25, 31, 44, 50 the sum is 180 and the count is 6, so the mean is 30. The middle two values are 25 and 31, so the median is 28. The range is 50 − 12 = 38.

Understanding your result

The mean uses every number, so one very large or small value pulls it. The median ignores that and shows the typical middle. If the mean and median are far apart, your data is skewed. A mode appears only when a value repeats.

When to use it

  • Average marks, prices or monthly expenses.
  • Compare mean and median salaries or house prices.
  • Check data before using it in a report.

Assumptions and limits

Up to 10,000 numbers are accepted. Anything that is not a number stops the calculation and is named in the message. This is a simple (unweighted) average. Use the GPA Calculator for weighted averages.

Frequently asked questions

What is the difference between mean, median and mode?

The mean is the sum divided by the count, the median is the middle value, and the mode is the most common value.

When should I use the median instead of the mean?

Use the median when a few extreme values would distort the mean, as with incomes or property prices.

What if no number repeats?

Then there is no mode. The calculator says that no value repeats.

Can I paste numbers from a spreadsheet?

Yes. A column pasted from a spreadsheet arrives on separate lines, which the calculator reads.

Are negative numbers and decimals supported?

Yes. Use a minus sign for negatives and a full stop for decimals.
