Box plot comparison
Compare groups with documented quartiles, whiskers and outlier rules while keeping all observations in the report.
Paste comma-separated CSV with a header and 2 to 2000 complete rows. Use dot decimals with at most six decimal places and values from -1000000000 to 1000000000. No missing values are silently dropped. Extra columns are used only to preserve the original input in reports. Calculations use the required columns only. Processing stays on your device. Results use floating-point arithmetic. Charts show the supplied sample, not proof about a population. Use value and optional group columns, with at most 20 groups and group names up to 80 characters. Quartiles use type-7 linear interpolation at (n-1)p. Fences are Q1 minus 1.5 IQR and Q3 plus 1.5 IQR. Whiskers are the most extreme observed values inside the fences. Flagged values remain in the data. Flags do not prove bad data or statistically significant group differences. Search and sort change this comparison only. Copy result copies the summary. Download JSON or CSV for all observations, results, settings and method assumptions. Download SVG for the chart. One disposable worker per calculation, with a 10-second timeout.

How to use Box plot comparison
- Paste complete numeric CSV rows with the required headers. Preserve the original order for lag diagnostics.
- Choose the displayed method settings and review their assumptions.
- Read the chart and table, then download all observations, results and assumptions as JSON or CSV.
