Box Plot Generator

A box plot shows the distribution of a continuous variable using five summary statistics: minimum, Q1, median (Q2), Q3, and maximum. The box spans Q1 to Q3 — the interquartile range — and the line inside marks the median. Whiskers extend to the data extremes within 1.5× the IQR, and individual points beyond the whiskers are plotted as outliers. SciFig's box plot generator renders all five elements accurately from a plain-language description.

Describe each group name, sample size, and approximate quartile values in your prompt, or upload your raw data summary. SciFig's box plot generator for multiple groups places side-by-side boxes on a shared y-axis with distinct colors, consistent whisker rules, and a clean x-axis label for each group — exactly the layout this stats boxplot creator is built for.

In the standard Tukey box plot, whiskers extend to the smallest and largest values within 1.5× the interquartile range from Q1 and Q3 respectively. Data points beyond those limits are individually plotted as outliers. Some researchers extend whiskers to the full range (min–max) or to the 5th and 95th percentiles — specify which convention you need and SciFig's box plot generator applies it consistently across all groups.

Use a box plot when you want to highlight the five-number summary, median, spread, and outliers without assumptions about the underlying distribution shape. Violin plots add a density estimate but can obscure sample-size differences. Bar charts show only means and are less informative for skewed data. For comparing group medians and variability in research papers, this stats boxplot creator is the standard choice.

Outliers are data points that fall more than 1.5× the IQR above Q3 or below Q1. In a standard box plot they appear as individual dots or circles beyond the whisker tips. Extreme outliers — more than 3× the IQR — are sometimes marked with a different symbol. Describe whether you want standard or extreme outlier marking and SciFig's box plot generator plots them correctly.

Yes. Notched box plots display a confidence interval around the median — if the notches of two boxes do not overlap, the medians are approximately significantly different. Specify 'notched' in your description and this box plot generator renders the notch correctly on each box, making inferential comparisons more visually immediate for readers.
