What Is The Five Number Summary?

The five number summary is a set of basic descriptive statistics which provides information about a set of data. It identifies the shape, center, and spread of a statistic in universal terms which can be used to analyze any sample, regardless of the underlying distribution. It consists of 5 key metrics: the median value (the center), the range of a distribution (25th percentile to 75th percentile), and the maximum and minimum observed values.

Additional Measures - Seven Number Summary

For convenience, we've enclosed two additional measures (10th and 90th percentile) which can be used to generate a similar package known as the seven number summary. The additional two metrics gives you better visibility into what is happening at the tails of the distribution. While outliers and distribution tails are a small fraction of your data, they can frequently have a disproportionate impact on overall performance. For example, a group of likely voters may exhibit a range of satisfaction scores with a particular candidate - but only the top and bottom 10% is truly motivated enough to take action based on their opinions. In business, similar models can be used to explain customer defection to another supplier and contribution margin economics within a distribution business.

Data Storage

This tool is designed to make it easy to repeat statistical calculations. You can save your data to local device storage (if your phone or computer supports HTML5), allowing you to retrieve and edit data from past calculations. A list of saved datasets is provided below the main calculation area - click on the name of the dataset and the data table above will update. Important: these are locally saved only (cannot be accessed on other devices, are not sent to our servers, and will be deleted if your cache is cleared). If you need to save this data permanently or share it between devices (or with a colleage), send it as a link. Click on the dataset name to load it into the list of data points in the calculator, hit the calculate button, and copy the URL. You can easily email the URL to your colleagues or post it on a message board. When anyone clicks on the URL, it will contain the shared values.
