Hi,
You will have to report faithfully the message returned, you cannot use your interpretation of the message. Error messages are codified. Each one will correspond to very particular error conditions. I did check the manual for all possible error messages and there is none that states wrong info.

My hunch is that there are errors in your data, but I can't say what type of error: I do not have the actual message returned. Verify you data, item by item, and try again.

To make sure that the calculator is well configured to do statistics

  1. Press [STAT][5:SetUpEditor][ENTER]
  2. Press [2nd][0] (CATALOG) and press [PRGM] (C) to jump to the first command starting with C.
  3. Scroll down to [ClrAllListsts] and press [ENTER]
  4. Calculator replies Done
Restart your statistical data entry.

Hope it helps.
Thank you for rating this solution

How do i find grouped data in L1 and L2 on ti 82


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.

My TI-84 plus silver edition doesnt allow me to use the comma when using the 1-Var Stats button.. I can't use more then one list and I need the mean of both lists


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.

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.

When I go into the 1 Var-Stats menu, I need to type in L1 and L2 but my comma button will not work. It will only let me type in one list at a time, and if I put two lists in without a comma it says error....


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.

How do you find the standard deviation using the list function when you place values in two lists? (Casio fx-9750GII)


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 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 you turn frequency on when in the stats table mode on a casio fx-9750gii?


There is no such thing as turning the frequency on on the Casio calculators. Just enter your data in lists. Choose one List where you put the frequency information. When you want to GRAPH or perform CALCulations you have a TAB labeled SET corresponding to key F6:SET. When you press F6, a new screen open where you assign the list to the variables.
Here are a few screen captures to help you.

k24674_68.jpg

Press F2:CALC (or F1 Graph). The Tab SET appears at the bottom of screen

k24674_69.jpg

Press F6:SET
k24674_70.jpg
Higlight the line 1-Var Freq (or 2-Var Freq). The bottom of screen shows F1:1 and F2:LIST. If frequencies are not equal to 1, press F2:LIST to assign the frequency list. I entered 2.

k24674_71.jpg

List2 is now the frequency list.
k24674_72.jpg

Press EXE to perform stats.

k24674_73.jpg

See that n=19.
