Histogram bins include the final right edge. Choose R7 interpolation, or medians of halves that exclude an odd middle value. Whiskers stop at the observed values within the IQR fences; extreme values are marked and kept. Use 2 to 5000 values and 1 to 100 bins. These are descriptive conventions, not diagnoses.
Model, grammar and limits
IQR=Q₃−Q₁; fₗ=Q₁−c·IQR; fᵤ=Q₃+c·IQR
Limits: 256000 raw data characters, 5000 source records and 50000 cells in total; decimals up to 48 characters; up to 20 groups or contributions and 50 columns. Limits for exact and bootstrap methods are stated with each tool. Parsing and resource checks run before the calculation, and the worker stops after 15 seconds. Editing, canceling or resetting discards pending results.
Check assumptions, ties and missing values before drawing conclusions. Results show 10 significant digits; CSV keeps the numeric values and units. Exact enumeration means exact counts, not exact displayed decimals. Numerical tail zeros, floors and unavailable intervals are labeled. Nothing here is a diagnosis, proof of causation or validity approval.
Your data stays in this browser. The calculation runs in a local worker, and CSV and backup files are local downloads you choose to make. Your data is not sent anywhere or saved silently, so keep your original data. Input data, formulas and filenames are never sent. Only with your optional consent, Refentra sends aggregate counts of actions and outcomes, without input content.
