i've seen the t.a. for mt class carrying around his ti-89 and i'm wondering iare there programs and or special things that the ti-89 does that would be helpful in stat? confidence intervals? lines of least regeresision any of that?

Yeah, but I think a ti-83 will do all the stats calculations you need just as well.

4/12/2006 7:07:41 PM

yeah the 83 comes with the Stats package already. For an 89 you have to go on the internet and download it to your calculator. Not sure if there's a difference between the packages though.

you are better off not using a calculator if you can help it

from ap stat in highschool, i remember that the 89 was a lot easier to use. its more menu based, meaning that if you know what you are looking for its easier to find answers. the 83 required a lot more worrying about syntax.

and not so much as helpful in stat as it is in calc, but it does derivatives and integrals.

4/12/2006 10:53:55 PM

Yeah if you download the package for the 89 it can do all sorts of analysis and can plot bell curves, etc.

dude, it's ST311, the easiest class i've ever taken in college.

Been awhile since I've taken intro to stats, but having a calculator with a built-in tables was a helluva lot quicker (and more accurate) than looking them up every time.

stop, you should be fine with an 83 or an 89, I've used both for stat problems. Pick one and stay with it. If you have a good instructor, they should provide instructions for how to do stuff on either.

take it with Reiland. He's very easy.

the better question is there anything a TI-89 cannot do?

4/14/2006 2:24:05 PM

nCr(x,y) and nPr(x,y) have always been helpful for me. saves doing all that factorial shit manually. ive never taken 311, i took 371, but i would imagine everyone does combinations and permutations

I am in Stat 311 with Karuri this semester. Seriously, the only things you are going to need your calculator to do are add, subtract, multiply, divide and do things to the xth power. The class average is a 98, and I have SERIOUSLY never cracked my book. I had a Ti-86 for 5 years that just died and got the 89 since the 86's aren't made anymore and it takes even longer. You could defintely pass this class with a regular scientific calculator.

Don't take it too seriously, just get the A like everyone else!!

the 83 does nCr and nPr too
