    Should I change calculators for stats?

    I'm taking a summer course on stats. Currently I have a ti-89 and the instructor allows us to use any calculator, but he only has support for 83. If I want to use the 89, I need to download software or something. Are there any advantages of using the 89 over the 83? I like the formatting of the 89, how it is computer like and how you can edit values you have entered just by scrolling up.

    Stats wise, are there any other advantages though? Or disadvantages? I'm trying to decide if it's worth it to buy the 83 for this class.

    Me, I would stick with the 89. It has a wonderful stats program you get for free from education.ti.com. And it is easier to use than the program on the 83.
    Just use your graph link to download it.
    I have a Voyage 200 and it comes with these programs already installed.

    Here is a screen shot of the program from my 92. I downloaded it from the site.

    Here is the link to the program:

    Statistics with List Editor App for the TI-89 Titanium by Texas Instruments -US and Canada

    There are also other programs you can get for free from the same site. There is a polynomial solver which handles up to a system of 30 equations.

    Can the TI-89 do anything the 83 can't, possibly more efficient or faster graphing/calculations, special calculations, etc? If not it may take a lot more effort learning the program than what is layed out on the 83, right.

    Of course, the 89 does more than the 83. It does calculus, has pretty print, has a solver, etc,etc....

    As I said before, go to education.ti.com to see all about the various calculators.

    As far as I am concerned, the 89 is more user-friendly than the 83. My final advice, get one. You won't be disappointed...assuming you have to take the math classes to warrant it.
