How to Insert Data Lists on the TI-84 Plus
You can’t rename a data list on your TI-84 Plus calculator, so if you want to have a nifty name for your list, it is best to insert a list before you start entering your data. To insert a data list in the Stat List editor, follow these steps:
If necessary, press [STAT][ENTER] to enter the Stat List editor.
Use the arrow keys to place the cursor on the column heading where you want your list to appear.
Your list is created in a new column that will appear to the left of the column highlighted by the cursor (as shown in the first screen).
Press [2nd][DEL] to insert the new column.
The second screen shows this procedure.
Enter the name of your data list and press [ENTER].
The name you give your data list can consist of one to five characters that must be letters, numbers, or the Greek letter theta. The first character in the name must be a letter or theta.
Press [2nd][ALPHA] to place the calculator in Alpha-Lock mode. The A after Name = indicates that the calculator is in Alpha mode. In this mode, when you press a key, you enter the green letter above the key. To enter a number, exit the mode by pressing a again, and then enter the number. To enter a letter after entering a number, you must press [ALPHA] to put the calculator back in Alpha mode (as in the third screen). Press [ENTER] when you’re finished entering the name.
Press [2nd][ALPHA] to put your calculator in Alpha-Lock mode. This enables you to enter letters without pressing a each time.
If the name you give your data list is the name of a data list stored in memory, then after entering that name and pressing [ENTER], the data in the list stored in memory will be automatically entered in the Stat List editor.
After you have named your data list, you can press the down-arrow key and start entering your data. If the data you want to put in the newly named list is in another column of the Stat List editor — or in a list stored in memory under another name — you can paste that data into your newly named list.
