SOURCE: it never shows L1 L2 or L3..its stuck on just l4

You can always restore lost or deleted statistical lists by pressing the STAT button. In the menu list that is displayed, press 5:SetupEditor and ENTER. The content of the deleted lists will however NOT BE RESTORED.

SOURCE: in stat lists my list starts at l2. how do i start

Press the [STAT] key.

Use arrow to move cursor to SetUpEditor

SetUpEditor command echoes on main claculator screen.

Press [ENTER]

Calculator will answer Done

Press [STAT] and select [1:Edit]

Type in the values in your lists.

SOURCE: Lost L2 on the stat edit function

Go into the STAT:EDIT function and Highlight L3. Push 2nd DEL (INSERT), and Put L2 back in. If there was data in List 2, it should reappear.

I do not know what you mean by regulate, but if you want to perform a regression analysis using data from L1 and L3, all you have to do is to specify the lists to be used.

For example if you have to perform QuadReg on L1,L3,

- Press [STAT] button,
- then Right Arrow to select CALC(ulate)
- then [5:QuadReg]
- The command QuadReg echoes on main screen as QuadReg .
- At this point press [SHIFT][1] to select (L1), then [COMMA], then [SHIFT][3] to select (L3) , and finally [ENTER].
- The result will be displayed after regression is performed.
- If you want to save the regression equation in Y1 so as to graph it over the scatter plot you enter QuadReg L1, L3, Y1 [ENTER]

L1, L2, L3?

If you are doing statistics, Set MODE to 3. Stat.

Choose 1-Var or any regression model. If you press 1-var you will have two lists x and frequency.

For any regression model you have 3 lists x, y, and Freq(uency).

L1, L2, L3, are list names in the TI 83/84 Plus and the Casio graphing calculators.

I hope it helps

Run SetUpEditor to restore the list names L1, to L6

100->dim(L1) to set the dimension of L1 to 100

100->dim(L2) to set the dimension of L2 to 100.

Since you are going to store the random numbers in L1, you should use L2 as the FreqList. All elements of L2 should be 1. When you create it all its elements are 0. One way to fill it with 1's is 10 run the command

**L2+1>L2;** Add 1 to each number and store the results in L2 (overwrite the 0 values)

Perform a blank run of 1-var Stats to get the chance to set the default lists.

1-var Stats L1, L2 ENTER

Type in your command

**randNorm(64.5,2.5,100) STO> L1:1-var Stats L1, L2** ENTER.

Use the Catalog to type in the 1-var Stats commnad so that you can type in the Lists L1 and L2 without opening the 1-var Stats configuration screen.

Do what you have to do with the statistics you generated.

To rerun the two commands again, press [2nd][ MODE] to (QUIT)

or press the sequence [2nd][ENTER] to have the last (ENTRY) echo on the main screen. Press ENTER to run again

**randNorm(64.5,2.5,100) STO> L1:1-var Stats L1, L2** ENTER.

If you are performing 1-variable statistical calculations, that presupposes you have one set of data only. Technically all you need is ONE LIST where the data is stored (ex. L1) . However if you have some data elements that are repeteated, you may choose to create a second list where you enter r the frequency (L2 or other). Both lists must have the same dimension (length).

When you bring up the 1-var calculation menu , the list of data elements is specified on one line (Xlist) and the fequency List is specified on the menu line Frequency. Thus there is no need to enter two lists on the Xlist line.

When you bring up the 1-var calculation menu , the list of data elements is specified on one line (Xlist) and the fequency List is specified on the menu line Frequency. Thus there is no need to enter two lists on the Xlist line.

I have followed your description and entered bogus data in Lists L1, L2, and L3.

I hit STAT then CALC then Option 1, which is 1-Var Stats. In this context you have only one set of data. If the data set contains many repeated values you can enter the frequency for each (repeated) data item in List L2, inserting 1 if an item is not repeated.

Thus when you do 1-Var Statistics you have at most two Lists (L1 contains the data values, and L2 their frequencies).

If you press the 1-Var Stats calculation option, the calculator takes L1 as the default data list so you see List:L1 and the ALPHA cursor blinking

On the secoond line you see Frequency: and nothing else on the line.

On the third line you have Calculate.

If Your data is not in L1, you can change that by pressing the [2nd][2] (L2), or [2nd][3] (L3). Only one list is specified there, so no need for the comma to separate. (you are doing 1-var Stat).

If your frequency data is in L2 you must specify it on the line Frequency. However, since the ALPHA keyboard is activated you must deactivate it first by pressing the ALPHA key. After that press [2nd][2] to select L2 or [2nd][3] to specify L3

If there is no frequency list, leave the Line frequency empty.

what is the data you are inputting? try to make sure they're aren't any symbols

May 04, 2011 | Texas Instruments TI-83 Plus Calculator

You can't manipulate lists like that.

{5,10,15,20,25}[STO>]L1

{5,5,5,5,5}[STO>]L2

These will input your lists properly. I'm not sure what you're trying to do, but if you're just trying to divide every entry in L1 by 5 and store it in L3, you could accomplish that with:

{5,10,15,20,25}[STO>]L1

L1/3[STO>]L3

Also, this page gives a lot of helpful tips on using lists on a TI-83.

Hi vanman21,

You may have a plot on, other than the one your trying to use or, graph. You can press, [2nd] [Y=] and, [Arrow Up] to go to the plots and, make sure all other plots are off. As k_akima stated, your number of list elements may be wrong. You can display L1 and, L2 at the home screen or, in the plots menu and, make sure both list have the same length and, data is correct.

It is important to select L1 and L2 from the [2nd] [1] for L1 and, [2nd][2] for L2 on the calculator. If you type [alpha][L][1] won't work.

Next, press [STAT] [5]**:SetUpEditor** and, the SetUpEditor command will display at the Home screen for you. It is important to do this process before you start creating lists to be analyzed and, used on the calculator. This will save you a lot of hardships from data that is already being used and, in the calculator registers. You can also associate your list to your project so, that other data won't conflict and, cause errors.

You also should add the rest of the lists or, structure of the CubicReg(L1,L2,Frequency list,RegEQ). The SetUpEditor is a great tool to help you gain the proper structure. The default for frequency is sat at 1 if not used but, having a RegEQ (such as Y1), will help the calculator to calculate your data. Just remember to set the mode to Func before you use the SetUpEditor.

If you have any questions, just post a comment and, I'll respond quickly.

2. To clear the list L1 completely

Press [STAT][4:ClrList]; command echoe on main screen as ClrList . You must specify what list you want to clear. To clear L1, you insert at the place of the cursor L1 and press [ENTER]. But to insert L1, you press [2nd][1] (L1) and press [ENTER].

3. Clear L1 and L2 completely you do as in point 2.

Press [STAT][4:ClrList] [2nd][1] [,] [2nd] 2 (L2). On screen command appears as ClrList L1, L2. Press [ENTER] to execute it. Screen displays Done

4. To clear a number in a cell.

Press [STAT][1:Edit]. The list editor opens. Move cursor to the top of the list, say L1. and highlight the heading

The whole list appears on the commande/edit line.

Press [ENTER].

Cursor moves to the entry line where all elements on the list appear between { }.

Use the cursor to the value you want to remove and press [DEL]. Do not leave unneeded commas.

Hope it helps.
