Assuming you already have L1 and L2 stored:

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

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.

When I push stat abd then edit, all that comes up is a list with "name" at the bottom of the screen. How do I get off that ?


Each "list" has to have a name. Usually, the lists are named L1, L2, L3, L4, L5, L6 ect. but you can give them text names as well.
To name the list, go to Stat--> Edit --> Input a name--> Enter To input a name, either do 2nd --> L1,L2,L3 ect.. or use Alpha --> Name

When I entered my data in L2 because in L1 I don't know what happened is not on the screen then I press STAT and select CALC, then select 1- Var Stats and press enter I should be able to see the mean,...


When you select 1-Var Stats, specify L2. If you don't specify a list, the calculator will assume L1.

You can recreate L1 by pressing
2ND [{] 1 STO 2ND [L1]

{ is on the ( key.
L1 is on the 1 key.

I have a trouble with my ti-83 plus. are there any body there can help me out? when i click on STAT to load my number on, but on the L1,L2, L3...and so on, it was disappear maybe somehow i delete them...


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.

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.
