By the Numbers
How to Make a Box and Whisker Plot
From data to finished chart in three simple steps.
Choose Your Input Mode
Select 'Raw values' to paste individual numbers or 'Manual summary' to enter pre-calculated quartiles. The tool adapts to what you already have.
Paste 20 exam scores per class, or enter Q1=55, Median=72, Q3=88 directly.
Add Your Categories
Click 'Add category' to compare multiple groups. Name each group, assign a color, and enter its data independently.
Add 'Control Group', 'Treatment A', and 'Treatment B' with separate value sets.
Customize and Export
Adjust orientation, box width, opacity, axis labels, and legend visibility. Then download as PNG or SVG, or grab an embed code.
Switch to horizontal layout, add axis labels, and export as SVG for your research paper.
Who Uses a Box and Whisker Plot Maker?
Box plots are the go-to chart for anyone comparing distributions across groups.
Compare Student Performance Across Groups
Teachers and researchers use box plots to show score distributions, identify at-risk students, and present findings in peer-reviewed papers without statistical software.
Summarize KPI Distributions for Stakeholders
Analysts and data teams use box and whisker plots to visualize sales ranges, response times, or customer metrics across product lines or regions in a single glance.
Present Clinical or Lab Data Accurately
Box plots communicate variability and central tendency in clinical trial results, lab measurements, or environmental data — essential for honest data reporting.
Monitor Process Variation
Manufacturing and operations teams use box plots to spot process drift, compare machine performance, and flag outliers that signal defects.

Frequently Asked Questions
What is a box and whisker plot?
A box and whisker plot (also called a box plot) is a chart that summarizes a dataset using five key statistics: minimum, first quartile (Q1), median, third quartile (Q3), and maximum. The 'box' spans Q1 to Q3, the line inside shows the median, and the 'whiskers' extend to the data extremes or to 1.5 times the interquartile range. Outliers beyond the whiskers are plotted as individual points.
Do I need to calculate quartiles before using this box and whisker plot maker?
No. In 'Raw values' mode, you just paste your individual data points one per line and the tool calculates min, Q1, median, Q3, and max for you automatically. If you already have summary statistics, switch to 'Manual summary' mode and enter them directly.
Can I compare multiple groups in one box plot chart?
Yes. Click 'Add category' to include as many groups as you need. Each group gets its own box with a distinct color, and all groups are displayed side by side on the same axis for easy comparison.
What is the difference between Tukey whiskers and min/max whiskers?
Tukey whiskers (1.5 × IQR) are the standard in statistics — they extend to the last data point within 1.5 times the interquartile range, and any points beyond that are plotted as outliers. Min/max whiskers simply extend to the smallest and largest values in the dataset, showing the full data range without separating outliers. Tukey is recommended for most analytical contexts.
How do I make a horizontal box and whisker plot?
In the Display Settings panel, find the 'Orientation' option and select 'Horizontal.' Your chart flips instantly — no rebuild required. Horizontal layouts work well when you have long category names or want to fit the chart into a landscape slide.
