Texas Instruments - TI-89 Titanium Graphic Calculator

Q: Is this calculator able to solve LINREG, QUADREG, and CUBICREG regressions?

Yes, this calculator does statistical regression. Push APPS, choose data/matrix, 3. New, pick any variable, enter on the table for your x and y data under c1 and c2 if you are doing quadratic regression per se. When you are ready for regression, push F5: Calc, and pick your regression type, set x... to c1, and y... to c2 per your table's field names, change Store RegEQ to ... y1(x) or y2(x) or whatever you would like to use from the drop down menu. When you are ready to process your data into a regression, press ENTER. The next window will show your coefficient values.

Q: I need a ti84 for my statistics class. Would this one work or just confuse me more.. ?

You could ask the instructor if the TI 89 would work ok for your class. Some classes are highly focused on instructions for a particular calculator and others are not. The instructor could tell you so. The TI 89 will work fine for statistics. If the TI 84 is recommended for your course, that may be a better purchase cost wise and if the extra functions may make it more confusing to use. On the other hand, if you value having more features and can zero in on the ones you need, this may be a better buy than having to buy yet another calculator for a class recommending a higher level calculator.
