Frequently asked questions
What's the difference between mean, median, and mode?
The mean is the sum divided by how many numbers there are (the everyday 'average'). The median is the middle value when sorted. The mode is the value that appears most often.
What if there's no repeating number?
Then there's no mode — the tool shows 'None' when every value appears only once.
Can it be more than one mode?
Yes — if several values tie for the most occurrences, all of them are shown.
Is my data uploaded?
No — everything is calculated locally in your browser and nothing is sent to a server.
