TI-84 back to factory setting

How do I get the TI-84 Silver Edition back the factory settings? Somehow in the STAT function I deleted the L1 column and don't know how to get it back. I don't want to continue pushing buttons as I don't know what other things I might do in the process.

You actually don't need to restore factory settings for this. I did it accidently and fixed it quickly.

Go to Stat > Edit...

Scroll over until at the bottom of the screen it asks for a name. Press 2nd > 1. L1 should appear, so now, just press enter.

Or just go to Stat > SetUpEditor...

I need to enter two columns of,values, x and y, to determine the linear equation but my table,only,displays the x column. How do,I get the y column back to enter numbers in?

Use the STAT function
Enter independent x_variable in L1, and y-variable in L2
To do calculations, Look under CALC (see 3rd screen capture).

Ti 84 plus silver edition will not fit a linear model to plotted points. when I use the function vars>stat>EQ>RegEQ it transmits incomplete data in to Y=.

Your data must be in two lists L1 (for x-values), and L2 (for y-values). This is the default setting. Open the STAT utility, go to the regression models. Select your model then press ENTER. The command echoes on the main screen. For example let the regression be something called LinReg.
On the main screen you see LinReg
Complete the command line as follows
LinReg L1, L2, Y1, ENTER
You see the statistics including the regression equation.
If you go to Y= Editor you will see that Y1 contains the regression equation.
If you have already drawn the scatter plot for your data, pressing GRAPH will superpose the scatter plot and the regression curve., and you will be able to judge the goodness of the fit.

I want to enter data into two lists, but when I click stat, enter, I dont see a L1 column, it only starts at L2. Even if I scroll left, I can't seem to find it.

You probably deleted it as a list variable. No matter, you can restore it (without its old content).
  1. Press the [STAT] key.
  2. Under the [EDIT] menu you see a list of options.
  3. Press [5:SetUpEditor] then [ENTER]
  4. All the default lists will be restored.

I am trying to do a box plot with a TI-84 Plus Silver Edition. I've entered my data values into L1, turned on Plot 1, chosen the box plot, and made sure X1 was set to L1. I keep getting ERR: INVALID DIM....

Hey. I had the exact same problem as you and all I could do was reset the settings to the default settings on the calculator. All you have to do is turn the calculator on, his 2nd (it should say mem right above it). Then click reset then RAM.

In my stat function, instead of L1, L2 and L3 columns appearing consecutively,only L4 (first) to L11 is appearing. how do i change it to L1 and so on

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.

Invalid dimension

Most of the time when you get the "invalid dimenstion" error, either list 1 or list 2 is longer than the other. Check your data and make sure you there are not more numbers in one list than in the other.

Another posssibility is that when you tried to clear list one, you may have deleted list one. If this is the case, you can get the column labeled list one back by pressing stat, then select set up editor form that menu which will take you back to the home screen. Press enter and the word done will appear. Now when you go back to stat edit, list one will be there.

Deleted y column in TABLE

I do not think that you can DELETE it, you probably just cleared the equation, just put another equation into Y=, and it will work.

otherwise, if you don't have any programs you need or so... just press 2nd +

Scroll down to reset, and press clear RAM

nb: Y1 could be find from (VARS) -> (Y-VARS)->(1:Function...)
