How to Sort Data Lists on the TI-83 Plus
You can use the TI-83 Plus graphing calculator to sort your statistical data that appears on your data lists. To sort data lists, follow these steps:
Press  to sort the list in ascending order, or press  to sort it in descending order.
Enter the list name.
To sort a default named list such as L1, press [2nd] to enter its name. If you’re sorting a user-named list, first press
to insert the letter L and then enter the name of the list. Inserting the letter L tells the calculator that what follows this letter is a data list, as shown in the first line in the first picture.
If you want to sort rows according to the contents of the data list you entered in Step 3, then (after completing Step 3) enter the names of the other lists, separated by commas. For example, the third line in the first picture is the command needed to rearrange the rows so the data in the second column is in ascending order.
Press [ ) ][ENTER] to sort the list, then press [STAT] to view the sorted list.
The second picture shows the rows rearranged so the second column is in ascending order.
