Navigating the LIST Editor
The LIST Editor is a powerful tool that allows you to create, edit, and manage lists of data on your TI-84 Plus CE calculator. To access the LIST Editor, press the [2nd] key followed by the [LIST] key. Once in the LIST Editor, you can use the arrow keys to navigate through the list. To select a list, press the [ENTER] key. To edit a list, press the [EDIT] key. To delete a list, press the [DEL] key.
The LIST Editor has a number of features that make it easy to manage your lists. For example, you can use the [SORT] key to sort the list in ascending or descending order. You can also use the [CALC] key to perform calculations on the list, such as finding the sum, average, or standard deviation. Additionally, you can use the [STAT] key to perform statistical analysis on the list, such as finding the mean, median, or mode.
The LIST Editor is a valuable tool for anyone who uses their TI-84 Plus CE calculator for math or science. By understanding how to navigate the LIST Editor, you can take advantage of its many features to make your work more efficient and effective.
Adding Elements to the List
To add an element to the list, use the “Ln( command, where “n” represents the number of the list to which you want to add an element. For example, to add an element to List 1, use “L1(. The element can be any type of data, such as a number, a variable, or a string.
There are several ways to enter an element into the list. One way is to type the element directly after the “Ln( command. For example, to add the number 5 to List 1, use “L1(5″.
Another way to enter an element into the list is to use the “Ans” variable. The “Ans” variable stores the result of the previous calculation. To add the result of the previous calculation to List 1, use “L1(Ans”.
You can also use the “STO→” command to add an element to the list. The “STO→” command stores the value of the expression on the left side of the command into the variable on the right side of the command. To add the value of the variable “x” to List 1, use “L1(x”.
Command | Description |
---|---|
Ln( | Adds an element to the list. |
Ln(5 | Adds the number 5 to List 1. |
Ln(Ans | Adds the result of the previous calculation to List 1. |
Ln(x | Adds the value of the variable “x” to List 1. |

Using the List in Programs
You can use the list in programs to store and manipulate data. To access the list in a program, use the L1 variable name. For example, the following program stores the value 5 in the list L1 and then prints the value of L1:
“`
L1 <- 5
Disp L1
“`
You can also use the list to perform calculations. For example, the following program calculates the sum of the values in the list L1 and then prints the result:
“`
L1->L2
L2+L2->L3
Disp sum(L3)
“`
You can also use the list to create graphs. For example, the following program creates a scatter plot of the values in the list L1:
L1->L2
L2+L2->L3
Plot1: Plot(L2, L3)
Here is a more detailed explanation of the syntax for the list commands:
Command | Description |
---|---|
L1 <- value | Stores the value in the list L1 |
Disp L1 | Prints the value of the list L1 |
L1+L1->L2 | Adds the values in the list L1 to themselves and stores the result in the list L2 |
sum(L1) | Calculates the sum of the values in the list L1 |
Plot1: Plot(L1, L2) | Creates a scatter plot of the values in the lists L1 and L2 |
