I'm receiving the message ERR: DATA TYPE 1:Quit 2:Goto I'm receiving this when I try to do stat in L1, L2, L3, and L4

It sounds like the problem may be caused by trying to store a matrix to a list variable.
A relative frequency table is typically created by taking a set of data and counting the number of times each value appears in the data. This count is then divided by the total number of data points to give the relative frequency of each value.
It is likely that L1, L2, L3, and L4 are lists that contain your data, and you are trying to use them to create a relative frequency table. However, it appears that L4 may contain a matrix, which is causing an error because matrices and lists have different data types and cannot be used interchangeably.
To fix this, you will need to identify where the matrix is coming from and convert it to a list, or use a different variable that is a list. Additionally, you can check the data types of your variables by using a function like type() or class() before you create the relative frequency table.
If you are still facing issues, you can share your code and dataset or specific steps you are following to create the relative frequency table, then I can help you to identify and fix the problem.

Help lost my L1 or L2 on the Ti graphing calculator

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.

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!

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

To restore a deleted list name, press [STAT], then [5:SetUpEditor] and [ENTER]. The list L1,L2,L3,L4,L5, L6 will be regenerated (without the data).

Example: Enter the following x variables, and determine the sample and population standard deviations.
x = {1,2,3}

• Press [DATA] and begin to enter the data as indicated into the L1, L2 or L3 lists. To input a data point, type the value and press [ENTER]. Press the down arrow key to move on to the next data point.
• Press [2nd], [STAT], and then choose 1-VAR.
• For the "DATA" option, choose the listname the data is stored in (L1, L2 or L3). For the "FRQ" option, choose "ONE" since this data does not include a frequency list.
• Arrow down to "CALC" and press [ENTER].
  
  Answers should be as follows:
  3:Sx (Sample Standard Deviation) = 1
  4:sx (Population Standard Deviation) = 0.816497
• Press [2nd] [MODE] to exit STAT mode.

If you have a frequency list it must be entered in a statistical list, L2, L3, ...or L6.
If the frequency of all elements is 1 you do not need to enter the frequency in a list. When you go to draw the box plot, the frequency will be set to 1.

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.

Assuming you already have L1 and L2 stored:

2ND L1 ^ 2 STO> 2ND L3 ENTER
2ND L2 ^ 2 STO> 2ND L4 ENTER
