Question about Texas Instruments TI-89 Calculator

I had this problem. What fixed it for me was clearing all of the lists in the Statistics application and also in the stat app in the f2 pulldown menu select Plotsoff. After that it worked fine

I simply made certain the plot used cooresponded to what was open in the stat app. This solved my problem.

You attempted to use two or more lists, matrices, or vectors as arguments, but the dimensions of all arguments are not equal, such as {1,2}+{1,2,3}

From the manual:

- You entered an argument with an inappropriate dimension.
- You entered a matrix or vector dimension less than 1 or greater than 255 or a non-integer.
- You attempted to invert a matrix that is not a square matrix.

It is most likely that the lists you are using as input data are of unequal lengths: One has fewer elements than the other.

I just created a small data set in two lists of unequal length. I was able to draw the scatter plot, but when I wanted to get a regression curve the error message popped up.

Start by creating the data lists.

CREATE THE X-LIST

Using Tab to move from one line to the next, configure the calculator as seen on the next screen.

And the last line is at the bottom of the next screen capture

The statistical results will hence be displayed in the C[] column.

Use TAb to move focus to OK, and press ENTER.

Here they are.

You can recognize each statistical results, RegEq is y=mx+b. You also have m, b, r^2, and r. The residuals appear on the next row. By highlighting the cell with the {0.,0...0} you can display the hidden values

Here you have all you asked for. But you can go further by drawing the curve.

The regression equation is stored in function f1, so you have to draw the f1 function. .

DRAWING THE REGRESSION CURVE

Press the HOME button

Highlight and select [2:Graphs and Geometry]

At the bottom of the screen there is a command line with f2(x)=

Use the UpArrow to display the f1(x)= equation

Press ENTER to draw the function f1

I think I have to stop here. There is enough material to get you started.

I left for you the part where you draw the data points. read the user manual.

CREATE THE X-LIST

- Press Home.
- Use navigation pad to Highlight [3: Lists and Spreadsheets]
- Press Enter
- A list opens with cursor in Cell A1.
- Use UpArrow to move the cursor to the header of the list and give it a name, say X.
- Press Enter. Cursor moves to Cell A1
- Enter an X-value in each cell and press ENTER to move to next cell:
- Type 1, and press ENTER. Say Yes to overwrite message by pressing OK.
- Enter 2,3,4,5,6,7,8,9,10 (just a bogus sample).

- After typing 10 in cell A10, press ENTER to validate.
- Use the Navigation pad to move cursor to the head of the B column.
- Give it a name , say Y.
- Press ENTER, Cursor moves to cell B1.
- As for X-list, enter the Y values. Here is a sample (-2, -1, 0, 1,2,3,4,5,6,7). After you type value in B1, accept the overwrite message by pressing OK. Type the other values.
- Make sure that the X-List and Y-List have the same number of elements, otherwise you will have a dimension mismatch error.

- While the lidt is still displyed, prress the Menu key
- Highlight [4:Statistics]
- Use Right Arrow to unfold submenu list and select [1:Stat Calculations]
- Use right Arrow to unfold the submenu list and
- Select [3:Linear regression (mx+b)] or [4:linear regression (ax+b)]

Using Tab to move from one line to the next, configure the calculator as seen on the next screen.

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 GRAPH F1 to enter the equation editor.

Plot1 Plot2 Plot3 on the top line of the equation editor displays the on/off status of each stat plot. When a plot name is highlighted, the plot is on. To toggle the status, press up, left, and right to place the cursor on the name, then press ENTER.
