Stat Editor Window Menu and Button This section explains the operations you can perform using the menus and buttons of the Statistical application’s Stat Editor window. To do this: Open an existing list (page 7-2-3) Close the currently selected list (page 7-2-4) Jump to line 1 of the current list (page 7-2-3) Jump to the line after the last line of the current list (page 7-2-3)
Page 382: Stat Editor Window Status Bar
Stat Editor Window Statu Bar The status bar at the bottom of the Stat Editor window shows the current angle unit setting (page 1-9-5), statistics View Window setting (page 7-3-2), and decimal calculation setting (page 1-9-5). If you see this: It means this: The angle unit setting is radians.
Page 383: U Ing Stat Editor
7-2 U ing 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. Ba ic Li t Operation 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.
Page 384 Creating a Li t A list starts out with an initial default name like list1, list2, list3, etc. The Stat Editor allows you to generate list data (list variables) quickly and easily. Note • The Stat Editor window has six default list variables, named “list1” through “list6”. These lists are system variables that are defined by the system.
Page 385 To jump to the fir t or la t line of a li t (1) Select any cell in the list. (2) On the menu bar, tap [Edit]. (3) Select one of the following commands to perform the type of operation you want. To do this: Move the cursor to line 1 of the list Move the cursor to the line following the last line that...

Page 390: Sorting List Data
• Note that inserting a cell does not affect the cells in other lists. If you insert a cell in a list that is aligned with another list, the lists will become misaligned when the cells underneath are shifted downwards. Sorting Li t Data You can use the procedures in this section to sort the data of a list in ascending or descending order.
Page 391: Clearing All Stat Editor Data
