Using Stat Editor

When you start up the Statistics application, the Stat Editor window shown
to the right appears on the display.

Stat Editor is a tool for creating and maintaining lists (list variables), and it
plays a very important role in ClassPad statistical calculations. ClassPad
uses lists as data sources for statistical calculations and for statistical
graphing. You can specify data by its list name.

The list name is located in the cell at the top of each list. The initial default
Stat Editor window shows six lists (columns), named list1 through list6.

List name

Basic List Operations

You can use the Stat Editor window to input and edit the data in the initially displayed list1 through list6. You
can also recall list variables you created with the Main application* and create new list variables.
