Boxplot Maker

Boxplot Maker is a statistical visualization tool designed to create box plots and calculate key summary statistics for numeric datasets. Whether you are analyzing experimental data, preparing a research report, or studying statistics, this boxplot maker provides clear graphical representations of data distributions.

Key Features

Statistical Summary Calculation

Enter raw numeric values to automatically compute essential descriptive statistics:

- Sample size (n)

- Minimum and maximum values

- First quartile (Q1)

- Median (Q2)

- Third quartile (Q3)

- Mean and standard deviation

- Interquartile Range (IQR)

Outlier Detection

The app automatically calculates upper and lower fences using the standard 1.5 times IQR rule (1.5 * IQR). Data points falling outside these boundaries are identified as outliers and plotted individually. You can choose to display or hide outliers on the chart based on your analysis requirements.

Distribution Shape Analysis

Beyond the standard 5-number summary, the app calculates distribution skewness and excess kurtosis to help you understand data symmetry and tail thickness.

Multiple Dataset Comparison

Add multiple datasets to generate side-by-side box and whisker plots on a single scale. Compare distributions, medians, and spreads across different experimental groups or data categories.

Customizable Plot Options

Tailor chart displays to your presentation needs:

- Switch between horizontal and vertical chart orientations.

- Customize box colors, line colors, and line widths.

- Toggle background themes between light and dark settings.

- Enable or disable outlier plot points.

Report Sharing

Export and share formatted summary statistics directly via text or messaging apps for easy inclusion in research papers, lab reports, or class assignments.

How to Use

1. Enter or paste numeric values separated by commas, spaces, or line breaks.

2. Label your dataset and select your preferred box plot color.

3. Add additional datasets if you need to compare multiple groups.

4. View the generated box plot and summary statistics instantly.

5. Export or share the statistical summary results.

Target Audience

This boxplot maker is designed for:

- Students learning statistics, probability, or data analysis.

- Researchers and scientists visualizing experimental data.

- Data analysts requiring quick box plot generation.

- Educators presenting 5-number summary concepts and data distributions.

No account creation or registration is required. All data parsing and statistical calculations occur locally on your device.
