How are outliers detected?

Using the IQR method: values beyond 1.5× the interquartile range from Q1 or Q3.

Is variance sample or population?

Sample variance (dividing by n-1) is used, the common default for datasets.

What separators can I use?

Commas, spaces, tabs, semicolons, or new lines all work.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
