Probability and Statistics > TI 83 for Statistics > TI 83 List

One of the first things you’ll need to do in statistics is to create a TI 83 list for data. Many functions on the TI 83 can be done without lists (by entering a string of numbers on the home screen), but creating a list offers several advantages including:

- You only have to type your list of data in once. This is especially useful if you want to perform a string of functions. For example, if you wanted to find the mean, then the standard deviation.
- Creating a list opens up a wide range of graphing functions. For example, you can turn on and turn off different plots on your graph.
- If you make a mistake, it’s easier to correct that mistake in a list. Otherwise you would have to re-enter the data.

In many cases, you’ll want to **clear the list data before you start**. If you know that you have a blank list (i.e. if your calculator is brand new) then you can skip the first section and scroll down to **Input your TI 83 List Data**.

## 1. Clear the TI 83 List Data

Step 1: Press the STAT button and then press 4 (clrList).

Step 2: Press the 2nd key and then press the number of the list you want to clear. For example, to clear list L_{1}, press 1 and to clear list L_{2}, press 2.

Step 3: Press ENTER to clear the list.

## Create your TI 83 List Data

Step 1: Press the STAT button and then press ENTER to go into “edit” mode.

Step 2: Type a number (for example “12”) and then press the ENTER key. Continue entering numbers, pressing the ENTER key after each entry.

## Name Your List

The TI 83 has six built in lists (L1, L2, L3, L4, L5, L6). If you want more:

Step 1: Press STAT then ENTER.

Step 2: Use the cursor keys to arrow over a list name. Then right arrow to the far right until you find a list with a blank name field.

Step 3: Type a name for your new list and then press ENTER.

**Tip:** To enter data into a different column, use the arrow keys at the top left to move the cursor to the next list over.
