My 1-var stats button is not working it says the

I am not sure I understand but if it the same problem as in your other posted question, here is what I wrote.

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.

Pay attention to the name: 1-var statistics mean you have ONLY one list of data. So you cannot use two. However if some data values are repeated you may choose to create a FREQuency list. So at most you have two list, one for the data values and the second for their frequency.
When you use the 1-var stat, specify the list that holds the data value (Xlist) and one the FREQ line specify the list that has the frequency

If your data values are in L1 and L2 or any pair of lists, then you should do 2-var stats. You will get the stats of both lists, you can also perform regressions, etc.

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.

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.

It depends what the two list mean.
If you are doing 1-var statistics you may want to enter the frequency of a data element (if some are repeated) in the list L2.
In that case when you run the CALC 1-Var , you first press the F6 key to set the lists Data List1, and Frequency List 2.
Once you set the lists, press the F1 key to select 1-var. The calculator will give all the statistics of the distribution.

If you are doing 2-var stats SET the lists and press F2 2-var. The calculator will give you the x-statistics, followed by the y-statistics.

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.

1. Enter the data using the [STAT][EDIT].
2. Once you finish populating your lists, press [STAT] button.
3. Three menu options are displayed EDIT, CALC, TESTS
4. Use right arrow to highlight CALC Menu.
5. Use DownArrow to scroll down the list to reach [C:SINEREG] or press Press [ALPHA][C:SineREG].
6. The command will echo on main screen.
7. Specify the lists to be used for the 2-var data and Press[ENTER] to execute command.

1. Press [STAT][5:SetUpEditor][ENTER].
2. Press [STAT][1:Edit..]
3. Enter your data in L1.
4. Press [STAT][CALC][1:1-Var Stats].
5. Command echoes on main screen.
6. If ONLY one list contains data, it must be L1.
7. When you do not specify the list in the command line it will take L1 by default.
8. If L1 is empty and the data is in L2, or another but L1, the name of list must be specified.
   

Hello,
1.Press [MODE], scroll to set Function graphing mode.
2.Press [STAT] [5:SetUpEditor], command is pasted in home screen. Press [ENTER]. Screen displays Done. This clears old values in lists

3. Press [STAT][1:Edit] to enter data.
Press [ENTER] after each number. Cursor moves to next row. After finishing the data of Listt L1, use arrow right and UP to the head of list L2. Enter the values in list L2. Press Enter after last element.

4. Press [Y=] to display Y= editor. Clear function Y1 and all functions or remove highlight from the = in Y2, Y3, etc.
5.Press [2nd][STATPLOT]1 to select 1:Plot1


The blinking cursor on ON means graph will be drawn. Type chosen is Scatter plot. Mark chosen is a dot.

Press [ZOOM][9:ZoomStat]

If you think that the curve look like a straight line you can try to do a linear regression.
Press [STAT] Arrow right to highlight [CALC]
Select [4: LinReg(ax+b)]



LinReg(ax+b) echoes on run screen. Press [2nd] L1 Press comma, Press [2nd] L2 press comma Press [VARS] Arrow right to select [Y:VARs][1:Function] [ENTER][1:Y1]

ENTER

That is the equation for the linear regression. As you see eqaution has been saved in Y1. Press [GRAPH] to get the data and the regression curve drawn on same graph.


Hope it helps.
