Summary
Private by design. This tool runs entirely in your browser — nothing you enter or add is uploaded to any server.
How it works
- Tokens are split on commas, spaces and line breaks, then parsed as decimals.
- Mean is the sum divided by the count. Median uses the middle value or the average of the two middle values.
- Mode lists every value that appears most often. If every value appears once, there is no mode.
Examples
- 4, 8, 15, 16, 23, 42, 8 has mean 16.571 and mode 8.
- 1 2 3 4 has median 2.5 because there are two middle numbers.
- A blank line between numbers is ignored.
Frequently asked questions
Are negative numbers allowed?
Yes. A leading minus is part of the number. Other characters make that token invalid.
