In the main calculator screen, press [2nd][Y=ĀØto enter the STAT PLOTS.

Press 4:PlotsOff to decativate all plots, then activate say Plot1.

1. Press 1:Plot1. Use arrow to highlight ON and press ENTER.

2. Use the DownArrow to move cursor to the line Type:

3. Select the plot type. (On this line only the right or left

arrows will allow you to select a type.)

Select the type and press ENTER.

4. Use DownArrow to move cursor to the XList line.

5. If the default (L1) suits your needs, press ENTER.

If not chage the list label to the correct one.

6. Do the same with the YList label.

I will give you a solution for a ti-83 Plus or ti-84 Plus calculator as they are very similar.

You should hit the [stat] or [stats] button as I forget which it is. Then hit [enter] which will bring you to a stats list editor of some kind. You will want to enter the data for your x-axis in L1 and the data for your y-axis in L2. Once you have completed your lists, hit the [stat] button again and then click [right] or the right arrow in order to move to the section of calc. from number 4 down it will help create a graph of that type of function. You desire a cubic function so it is number 6, so you hit [enter] on number 6 and then you will be at the home screen with CubicReg already written. You just have to complete the statement and it will do it for you. hit the [2nd] [1] and then the comma button, then [2nd] [2] and [enter]. that will do it for you. Also if you want the equation to appear in your y= menu, you can hit [2nd] [stat] and then search for the Y1, but make sure you have a comma between the L2 and the Y1.

Give the list a name then press ENTER. You have to tell the calculator which list you want to edit.

Oct 07, 2010 | Texas Instruments TI-83 Plus Calculator

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.

Easy:

1.) Turn it on ("ON" button)

2.) Hit the "STAT" button

3.) Hit the Right arrow key Twice

4.) Hit the down arrow key once or hit the "2" button

5.) Enter your Data into List one (L1) OR Right Arrow once and "ENTER" to just enter your statistics

To just Enter the Statistics:

Down Arrow once and Enter:

Hypothesis mean

Sample Mean

Standard Deviation

Number of Tests

and Either (not equal to)Ho , <Ho , or >Ho

Then either hit Calculate or Draw

A previously posted solution, taken from my Web page without permission, was removed by the admins at my request. The person who posted it should have asked first and should have credited me. Here is my solution:

==========================================

This message has several possible causes.

- If you get this when making some kind of plot, you probably forgot that you have one of Plot1 Plot2 Plot3 turned on, and it refers to two lists that don't have the same length. The cure is to press [Y=] and turn off the unwanted plot.
- If you’re actually doing something that needs lists, such as a regression, but your lists don’t have the same length, you get this message. Press [STAT] [1] and check your lists.
- You also get this message when you give the TI-83 a list or matrix where it expected a variable or number, or vice versa. For instance, on the STAT PLOT screen, you may mean to press [2nd] [L1] but if you miss the [2nd] you actually type a Y. In the same way you might type a Z where you intend to type L2.
- Karl Wein offers another possibility. You can create a list called L1, but that is not the same as the predefined list called L1 (note the small-capital L), and of course similarly for lists 2 through 6. If you accidentally delete a predefined list from the editor, make sure to bring it back with the SetUpEditor command.

Yes you can use it, here is the formula: Y= V(t+ (i/c))^(tc) V=amount put in, t=time, i=intrest rate, c= amount of times it is compounded.

(I know this because I have a TI-83 calculator)

you have one of your stat plots on that is what is messing it up. So either turn off the stat plots. Or just reset your calculator. hit 2nd then the plus (+) key then 7 then 1 then 2. Good luck

You're probably getting a dimension error 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.

I'm having the same problem and I tried turning off one of these stat plots but turns out I don't know how to do it, or how to tell if I did or not. Help please?

Thanks

Thanks
