You already have a list L1 archived in memory.

You have two choices. You can either choose another name or you can unarchive the existing L1. To unarchive a list, press 2ND [MEM] 2 4 then use the arrow keys to move the highlight to the line containing L1 (there should be an asterisk "*" in front of the name). Press ENTER and the asterisk should disappear. Press 2ND [QUIT] to return to the home screen.

SOURCE: Hi- on my Ti-84 plus

Even if you do not have L1 you can still graph: You have 6 lists to put data in. You are not required to use L1 but you will have to specify the lists. Be it as it may you can restore L1, which in all likelihood you deleted.
Press the [STAT] key and select [4:SetUpEditor] then press [ENTER]

SOURCE: Trying to use the solver

Some variable in your function is in archive memory. Press 2ND [MEM] 2 to get into the Memory Management menu. Press 1 to select All. Do you see a variable you're using in your function with an asterisk to its left? If so, navigate down to it and press ENTER to turn off the asterisk. Do this for as many variables as necessary, then press 2ND [QUIT] to exit.

Try the Solver again.

SOURCE: I am trying to drive a prediction equation. but

I assume you know how to enter data in your calculator. The keystrokes in the following pertain to TI92/92Plus/ Voyage 200 PLT. The main differences with the TI89/Ti89 Titanium is that the function keys F6,F7,F8 are not accessed directly but by the key sequences [2nd][F1], [2nd][F2], and [2nd][F3] respectively

1. CLEAN THE SLATE (so to speak) and ENTER DATA

In Home folder run F6: NewProb to reset the configuration.
Press Apps, and select 6: data/Matrix editor. Select a new data set
84e1901.jpg

Give it a name: here testing.

2133d3f.jpg

Press OK/ENTER, The data entry screen opens, enter your values.
0ab1602.jpg

When you finish press F2.PlotSetUp.

2. Statistical plot setup and scatter plot drawing

b142867.jpg.

Press F1:define to configure Plot1. Choose Scatter, then choose a mark for the data point. I select 5:Dot. and press [ENTER
0ee40be.jpg

Select the data column X=c1, Y=c2

65437f9.jpg

Press ENTER to save configuration. Press [CTRL] [GRAPH] On my TI92 the CTRL key is the [Diamond] key. On the following graph I changed the mark to a cross to see the data point better. I also played with the window dimension. You can also do that with ZoomStat. The graph remind me of a parabola (I know I chose the exact values)

7de9410.jpg

3. STATISTICAL CALC. AND REGRESSION ANALYSES.

Now we have to find the equation that fits these data best.
You press APPS 6:Data/ Matrix editor but you select current to return to your data set. You are taken to the data entry editor (Figure 3 above). In that screen Press F5:Calc to edit the type of statistics you want

On first line select the type of regression model : Linear Regression, QuadReg quadratic regression (or anything else available) X is from column1, Y is from column 2. Store RegEQ The regression equation in say Y1(x)

7c9f572.jpg

Press ENTER to save to get the Regression Equation. Here it is
As you can see I cheated: a perfect parabola. R^2 =1.

c46b604.jpg

And here the best fit represented on same graph as the statistical data

Usually you have to try different regression models, until you find the one that fits best the experimental data.

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.

I want to enter in numbers for L1 and L2, but when I go the TABLE there is no L1 or L2 column, only X, and there are numbers entered in the X column that I want to delete. How do I clear the X values,...


The table is where the calculator displays values from functions entered in the Y= page. To enter numbers into lists, press STAT and select Edit to get into the list editor.

Not Graphing


You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

If that's not it, post a comment and we'll go from there.

I can't open any progrmas on my TI-84Plus , it only gives : Error and 1:QUIT can you experts help me?THNX


Hello,
You should give the whole error message.
I created a bogus program and archived it.
Then I tried to execute it. I got the messages: ERR Archived 1:Quit 2:Goto. When I tried to edit it I got ERR:Archived 1:Quit.

Your program is archived. You must unarchive it.

To Unarchive. Press [2nd] [MEM][2:Mem Mgmt/Del] [ENTER]
Scroll down to [7:Pgrm]. Archived programs will have a star at the left. Highlight the program you want to unarchive and press [ENTER]. The asterisk disappears. Press [2nd][QUIT]. Your program is ready to run or to be edited.

Hope it helps.

TI-84 back to factory setting


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...
