7-2 Using Stat Editor

Lists play a very important role in ClassPad statistical calculations. This section provides an overview of list operations and terminology. It also explains how to use the Stat Editor, a tool for creating and maintaining lists.

Basic List Operations

This section provides the basics of list operations, including how to start up the Statistics application, how to open a list, and how to close a list. It also tells you about list variables and how to use them.

IWhat is a list?

A list is a type of data array that makes it possible to manipulate multiple data items as a group. A list has one column and can contain up to 9,999 rows. You can display up to 99 lists on the Stat Editor window.

List operations are performed using the Stat Editor window, which appears whenever you start up the Statistics application.

Lists are treated as variables, and like variables, are stored in a folder in the memory and can be manipulated using the Variable Manager. If a list is cleared from the display, it still exists in memory as a variable and can be recalled when needed.

Note

• See “Inputting Data into a List” for information about data input (page 7-2-4).

IUsing List Variables

The list name is located in the cell at the top of each list. List variable names can be used inside of calculation formulas, just like any other variable name. The initial default Stat Editor window shows six lists (columns), named list1 through list6.
