Mean, median, mode and more

Separate numbers with commas, spaces or new lines — any mixture works.

This free Average Calculator goes well beyond a single average and gives you the full picture of a list of numbers in one click. Paste or type any list — exam scores, daily temperatures, product prices, survey answers — and it returns the mean, the median, the mode, the range, the total sum, the count, and the smallest and largest values. Having all of these together matters, because each one tells a different story about the same data, and relying on the mean alone can be seriously misleading when a list contains one extreme value.

The median is the middle value when the list is sorted, which makes it a fairer "typical" figure for things like salaries or house prices where a few very large numbers drag the mean upward. The mode shows the most frequent value, useful for spotting the most common shoe size, score or answer. Separators are flexible: commas, spaces, tabs and new lines can be mixed freely, so lists copied from spreadsheets or documents usually work as pasted. Everything is calculated locally in your browser, and your numbers are never uploaded or kept.

Frequently asked questions

What is the difference between mean and median?

The mean adds everything up and divides by the count. The median is simply the middle number of the sorted list. When a list has one or two extreme values, the median usually describes a typical entry better than the mean.

Can a list have more than one mode?

Yes. If two or more values tie for the most appearances, all of them are modes and the calculator lists each one. If every value appears the same number of times, it reports that there is no mode.

What does the range tell me?

The range is the largest value minus the smallest. It is a quick measure of how spread out the numbers are: a small range means the values cluster together, while a large range means they vary widely.

How many numbers can I paste at once?

Thousands of values work fine, because the calculation happens instantly on your own device. Very long lists are handled the same way as short ones, including pasted columns from a spreadsheet.
