- Read the big number for the average, then check the grid below for every other figure. Press Calculate to save the tool to your recently used.
FAQ
What is the difference between mean, median and mode?
The mean is what most people call the average: add every number up and divide by how many there are. The median is the middle value once the numbers are sorted from smallest to largest (with an even count it is the average of the two middle values). The mode is simply the value that appears most often — a list can have one mode, several, or none if every number is unique. This tool shows all three at once so you can compare them, which is handy because a few very large or very small numbers can pull the mean away from the median.
Is anything I type uploaded?
No — it runs in your browser. Your numbers are used for plain arithmetic on your own device and are never sent to a server or stored anywhere. The calculator works offline and keeps your data private.
What counts as a valid number?
Whole numbers, decimals and negative numbers all work. Anything that is not a number is simply skipped, so you can paste a messy list with extra text and still get a clean result. If the box has no usable numbers in it, the result stays blank instead of showing an error.
