About Tukey Box-and-Whisker Plot Generator
Publication-grade Tukey Box-and-Whisker plot generator supporting single and multi-group experimental comparisons. Computes five-number summaries (Minimum, Q1, Median, Q3, Maximum), draws interquartile range boxes with whisker fences, and plots individual outlier points distinctly.
Key Capabilities & Features
- Multi-group comparative plotting: Compare Control vs Treatment groups side-by-side on a shared scale
- Standard Tukey fences: Whiskers extend to the most extreme data point within 1.5×IQR from the quartiles
- Distinct outlier plotting: Data points beyond the inner fences are plotted as individual red markers
- Five-number summary calculations: Minimum, 25th percentile (Q1), Median, 75th percentile (Q3), and Maximum
- High-resolution vector SVG output with crisp typography and responsive scaling

Frequently Asked Questions
What does the height or width of the box represent?
The box represents the Interquartile Range (IQR = Q3 - Q1), containing the middle 50% of your data observations.
How are the whiskers calculated in a Tukey box plot?
Whiskers extend to the lowest and highest observations that still fall within Q1 - 1.5×IQR and Q3 + 1.5×IQR, rather than the raw absolute minimum and maximum.
