7-2 Using List 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 List 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.
k What 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 List Editor window.
List operations are performed using the List 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).
k Using 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 List Editor
window shows six lists (columns), named list1 through list6.
