Stat Summary

Calculator Details

This calculator mimics Rstudio’s ‘summary’ function.

How to use:

1. Type or past in values with spaces or commas in between. Number of spaces should not matter. **(Update 10/15: you can now include {}()[] with no hiccups!)**
2. Press the ‘Get stat Summary’ button or enter to get results. *note: must use at least 4 numbers*

Method 1 does not include the median when finding Q₁ and Q₃ (only if n is odd. The median is not in the set if n is even).

Method 2 includes the median which can shift Q₁ and Q₃ slightly. Rstudio uses the second method.

How to know which method to use?

If you’re in school, ask your teacher. They will tell you if they have a preference. As stated earlier, Rstudio uses the method 2.

Ultimately, these methods only differ for small sets. So it is not too crucial unless you are being graded.

As a project

This is the third calculator uploaded to projecTym, but the first to include a text box for the numbers. The previous calculators made you choose your n first and then used individual inputs for each number. This calculator is for quick copy and paste and trusting that the user will put in acceptable inputs.
