You can't, the TI-30XA is a one variable statistical calculator, so you can't do two variable statistics with it.

You need to step up to the TI-35X or the TI-30X IIS

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.

How can you program games for a TI-30XA calculator. I mostly want to know if it is possible, what programming language is required, and any links that can help.


Do not even go there. The calculator is pretty basic and does not have memory to store instructions. If you want to take up programming ( a worthwhile endeavor) buy a graphing calculator such as a TI 89 itanium, a TI Voyage 200PLT, a TINspire, or a Casio Graphing calculator FX 9860 SD, ClassPad 330, or some top of the line HP calculators (HP 49G+, HP 50 G).

I bought it at a rummage sale and what a manual for it where can i get one? And is different from the TI 30X 11?


You can download the TI-30Xa guidebook from the manufacturer's web site at
http://education.ti.com/calculators/downloads/US/Guidebooks/Detail?id=6132

The TI-30Xa replaced the TI-30X within a year. The only enhancement was the added Constant key.

The TI-30XII, introduced about five years later, is a significantly different calculator, incorporating, among other things, a two-line display.

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
84e1901.jpg

Give it a name: here testing.

2133d3f.jpg

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

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)

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.

Linear regression


I already answered a Q like this - you can't do 2 variable statistics on the TI-30XA, it only does one variable statistic.

To do 2 variable stat like linear regression, you need the TI-36X or TI-30X IIS, or comparable HP, casio etc
