How to get l1 l2 l3 charts


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

Error stat


Are the data in L1 and l2 in any way related? If they are (being x-values and y-values of some data set) then you need to do regression analysis (2-var stats)
If they are not related (connected) you can calculate the mean of each group separately.
Do 1-var stat by specifying the L1 list first (may be the default), get your average of the values in L1. Then you can do 1-var stat on the data in L2 by specifying the list L2 on the command line.
1-var L2 ENTER
Note: What I am describing here is valid for the TI 83 Plus/TI84 Plus, but I suspect the steps are similar to the TI 82.

Multiple operations in single command on new TI84


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.

Hoe 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.

How do i restore L1 and L2 in "edit" if i deleted them?


So you have deleted the L1,L2 lists. Well their contents are lost and the lists are no longer there to be filled. Right?
Have no fear, they can be restored (without your valuable data).

Press [STAT]. The Stat editor screen display 5 sub-menus.
Select [5:SetUpEditor] and press [ENTER].
Press [STAT][1:Edit] and you now see L1, and L2, and the lists you did not delete.
Enter your data again in L1 and L2.

When one of my students went to stat plot, they got an error archive message


Hello,
Press [2nd][MEM][2: Mem Mgmt/Del][1:All] and scroll down to see if a system variable or other entity that is needed for graphing may have been archived. A variable that is archived has an asterisk next to it on the left.
To unarchive it press ENTER when the arrow reaches it.
You may be able to draw your graphs. It you are unable, I suggest you reset the Ram: Press [2nd][MEM][7:Reset][1:All Ram][2:Reset] [ENTER]. Press [CLEAR] to erase the message and restart the statistics.

Hope it helps.
