Free statistics calculators designed for data scientists. This Box and Whiskers Plot Maker:

  • Generates A Box and Whiskers Plot
  • Calculates Key Quartile Statistics

Using The Box and Whisker Plot Maker

Enter your data as a string of numbers, separated by commas. Then hit calculate. The Box and Whisker Plot Maker will generate a list of key measures and make a box plot chart to show the distribution.

For easy entry, you can copy and paste your data into the box plot maker from Excel. You can save your data for use with this calculator and other calculators on this site. Just hit the "save data" button. It will save the data in your browser (not on our server, it remains private). Saved data sets will appear on the list of saved datasets below the data entry panel. To retrieve it, click the "load data" button next to it. This is useful if you want to tweak the data and rerun it in the box and whisker calculator or pass it another statistical tool.

More About The Box and Whisker Plot Maker

This tool has two key purposes:

The box and whiskers plot is a common visual tool used for exploratory data analysis. This calculator is designed to make it quick and easy to generate a box and whiskers plot and associated descriptive statistics. Simple enter your data into the box plot maker and you will get a quick view of the shape of the distribution.

Interpreting a Box and Whiskers Plot

The core of the distribution is shown by the box in the plot. This represents the gap between the 25th percentile and the 75th percentile of the distribution, generally referred to as the interquartile range. This is usually a relatively dense region. This is particularly true if the data generated by the underlying process is normally distributed. The upper and lower lines denote the maximum and minimum values observed in the sample data. This gives you perspective on the outliers of a particular sample. Want to learn more about analyzing box plots? Statistics Canada published a good overview of using this statistical tool. Additional materials can be found here.

Finding the Range of a Set of Numbers

This tool is particularly useful if you need to find the range of a set of numbers and analyze it. The box plot generator provides both the interquartile range (distance between 25th and 75th percentile) and the total range (min vs. max) of a data sample.
