How to Sort Data Lists on the TI-84 Plus
The TI-84 Plus graphing calculator has many features that provide information about the data that has been entered in the calculator. You will accumulate a lot of data and will need to be able to sort it in order to properly analyze that data.
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.
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 shown is the command needed to rearrange the rows so that 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 that the second column is in ascending order.
