TI-89 StatsList Histogram Display Problem

So when i first installed the stats list editor program from the TI website (why this calc didnt come with the program is beyond me), the histograms I created displayed perfectly with the "ZoomData" command. Now for some reason, they display all out of whack with some of the data across the y axis, i can see some blank space below the x axis, and I can't figure out why. I have turned off all plots and functions, my y= is completely clear, and i have cleared all RAM as well.

Anyone know whats going on? I have a test coming up, and i just want to display my histograms cleanly and easily!

Thanks in advance.

Did you download 3rd party APP's or stuff not from the TI site? My programs work, by running some of them might bring the calculator back is all I can think of. raklein62@yahoo.com

I am trying to drive a prediction equation. but the book gives directions to aTI-84 and I have a TI-89. I have these steps "STAT, EDIT, L1, L2,STAT, CALC,LinReg(ax+b), ENTER" I have no clue how to make...


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

Give it a name: here testing.

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

When you finish press F2.PlotSetUp.

2. Statistical plot setup and scatter plot drawing

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

Select the data column X=c1, Y=c2

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)

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.

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.

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.

Ti-89 help


You create a program by using the program editor. Press the "APPS" key and select "Program Editor".

What type of data graph do you want? The TI-89 can plot Scatter, XYline, Box, and Histgram graphs. Use the "Plot Setup" screen to select the desired plot type.
