Delete and Edit Statistical Data on the TI-83 Plus
Sooner or later you’ll have to remove or modify the data that you’ve placed in a data list on the TI-83 Plus graphing calculator. The following list shows you how to do so.
Deleting a data list from the memory of the calculator:
To permanently remove a data list from the memory of the calculator, press [2nd][+][2] to enter the Memory Management menu. Then press [4] to see the data lists that are stored in memory. Use
to move the indicator to the list you want to delete, and then press [DEL] to delete that list. When you’re finished deleting lists from memory, press [2nd][MODE] to exit (quit) the Memory Management menu and return to the Home screen.
Although the calculator does allow you to delete a default list (L1 through L6) from memory, in reality it deletes only the contents of the list and not its name.
Clearing the contents of a data list:
When you clear a data list, the list’s contents (and not its name) will be erased leaving an empty data list in the calculator’s memory. To clear the contents of a data list in the Stat List editor, use the
keys to place the cursor on the name of a list appearing in a column heading, and then press [CLEAR][ENTER].
Deleting a column (list) in the Stat list editor:
To delete a column (list) from the Stat List editor, use the
keys to place the cursor on the name of the list appearing in the column headings and then press [DEL]. The list will be removed from the Stat List editor but not from the memory of the calculator.
Deleting an entry in a data list:
To delete an entry from a data list, use the
keys to place the cursor on that entry, and then press [DEL] to delete the entry from the list.
Editing an entry in a data list:
To edit an entry in a data list, use the
keys to place the cursor on that entry, press [ENTER], and then edit the entry or key in a new entry. If you key in the new entry, the old entry is automatically erased. Press [ENTER] when you’re finished editing or replacing the old entry.
