There is no L7 list. You can put your data in any available list. You can even create your own lists.
Anyway, to recover the L1,L2,L3, and L4,
Press [STAT][5:SetUpEdidor] [ENTER]
Calculator displays Done.

Press [STAT]. Under Menu EDIT, Press [1:Edit]
The List editor opens the L1,L2, etc. liststo let you enter your data.

How do i get l1 l2 l3 charts up


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.
However I have no idea what getting the charts up mean.
I hope it helps

My calculator is TI-83 plus. I get Err: data type every time I want to use lists to calculate something. For example I enter 5,10,15,20,25 in list 1 and 5,5,5,5,5 in list 2. Then in list 3 I type L1/L2,...


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.

When I push stat abd then edit, all that comes up is a list with "name" at the bottom of the screen. How do I get off that ?


Each "list" has to have a name. Usually, the lists are named L1, L2, L3, L4, L5, L6 ect. but you can give them text names as well.
To name the list, go to Stat--> Edit --> Input a name--> Enter To input a name, either do 2nd --> L1,L2,L3 ect.. or use Alpha --> Name

In my STAT-Edit, there's only L5, L6, L4 and a blank List.. and my L1, L2, and L3 are missing..i accidentally deleted them...how do i get them back?


Scroll to the blank sport (hit the left/right key a couple times) and then type in the missing list names.
So where the _ _ _ _ _ is hit 2nd then 1 for your L1, 2nd then 2 for your L2 and so on

In my precal class we are studying trigonometry graphing. On my calculator I made 3 lists L1, L2, and L3 when I go to graph and regulate the equation it only regulates the equation for both L1 and L2....


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,
  1. Press [STAT] button,
  2. then Right Arrow to select CALC(ulate)
  3. then [5:QuadReg]
  4. The command QuadReg echoes on main screen as QuadReg .
  5. At this point press [SHIFT][1] to select (L1), then [COMMA], then [SHIFT][3] to select (L3) , and finally [ENTER].
  6. The result will be displayed after regression is performed.
  7. 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]

I have data entered in L1 and L3. And I want to take the log of L3 in L2. But after I do that it gives me an error. How can I fix this.


Hi,
If the data in your L3 list contains only positive numbers there is no reason why you should not be able to calculate the log of the list and store that in L2.
  1. You open the list editor, [STAT][1:Edit]
  2. Use arrows to position the cursor on an element of L2.
  3. Use UpArrow to highlight the L2 heading (at the top of the list) and press ENTER.
  4. The data entry line will show L2= ..
  5. Erase anything that may be on the L2 entry line and type in
  6. [LOG] [2nd] [3] (L3) to enter the L3 identifier inside the log (
  7. Close the right parenthesis. Screen shows L2= log(L3)
  8. Press [ENTER]
  9. The L2 list will be populated with the logs of the elements of L3.
Hope it helps

In my stat function, instead of L1, L2 and L3 columns appearing consecutively,only L4 (first) to L11 is appearing. how do i change it to L1 and so on


Press Stat. Choose "set up editor" from this menu. You will be returned to the home screen. Press enter and you'll get the message "done". This should fix the problem.
