What's the difference between mean, median, and mode?

Mean is the sum divided by the count — the everyday "average." Median is the middle value when sorted (or the average of the two middle values for an even count) — less sensitive to outliers. Mode is the most frequently occurring value, or values, in the list.

What if every number appears the same number of times?

Then there's no meaningful mode, and the tool shows "None" — a mode only exists when at least one value repeats more often than the rest.

Can I paste numbers from a spreadsheet?

Yes — numbers separated by commas, spaces, tabs, or new lines (like a pasted spreadsheet column) are all parsed correctly.

Is my data sent anywhere?

No. All math runs locally in your browser — nothing is transmitted or stored.
