Frequently Asked Questions
What is the difference between mean, median and mode?
The mean is the arithmetic average, the median is the middle value when the numbers are sorted, and the mode is the value that appears most often. They can differ a lot when your data is skewed.
What happens if there is no repeating value?
If every number appears only once, there is no mode, so the tool reports the mode as "None".
Can I paste numbers copied from a spreadsheet?
Yes. The calculator splits on commas, spaces and new lines, so columns or rows copied from a spreadsheet will be read correctly.
What does range mean here?
Range is the difference between the largest and smallest number in your list, which shows how spread out the values are.
