Frequently asked questions

What's the difference between mean and median?

The mean is the sum divided by the count — it's pulled toward outliers. The median is the middle value when sorted, which is often a better "typical value" for data with extreme highs or lows (like income or home prices).

What if there's no repeated value?

Then there's no mode, and the result shows "No mode" — mode only exists when at least one value appears more than once. If multiple values tie for most frequent, all of them are shown.

How are numbers parsed from my input?

Anything separated by commas, spaces, or line breaks is treated as a separate number; entries that aren't valid numbers are ignored rather than causing an error.
