Frequently asked questions
- Commas, spaces, newlines, or a mix of all three — the parser splits on any of them and ignores anything that isn't a valid number.
- If several values tie for the highest frequency, all of them are listed as modes. If every value appears exactly once, the dataset is reported as having no mode.
- Both formulas exist for a reason — sample variance divides by n−1 to correct for bias when your data is a sample of a larger population. Check the labels next to each figure to see which one is shown.
- No. All the math runs in your browser — nothing you paste is sent to a server or stored, and no account is needed.
- No. It runs entirely in your browser — no software install, no account, no email required.
