Normal Distribution Canvas Application Example 

In this example the user is given a list of grades, which can be modified.  When the button is clicked a histogram and density plot is displayed and some statistical values are computed.

The complete application source code is available here for you to inspect and modify.  It uses the Canvas package to describe the interface, and a ScriptButton to implement an action.
