Your L2 list did not become L3, you just deleted it. To restore a deleted list (NOT ITS CONTENTS), press the [STAT] button, then, press the number to the left of SetUpEditor and finish with the [ENTER] command.

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

I am curently taking Statistics and when I hit "stat" then enter information into the L1, L2 , L3 area etc then I go to stat again and press calc and choose option 1 then in the list area I need...


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.

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.

Hope this helps!

When using the STAT>EDIT option


In order to create a list, press STAT->EDIT and scroll all the way to the right of the column titles. Once you go far enough (usually past L6), there should be a column with no title and when your cursor enters it, ALPHA-lock should come on. Enter any name into the title box for this blank column. In your case, you will want to press 2ND->L2 (which is the "2" key's alt. function). Then press enter or scroll down the page. You should now have a list with the name you entered among your lists and it should work just like any other list.

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.

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.
