Graphing, plotting, matricies, statistics, distirbutions, confidence intervals, many regression techniques, this thing does it all.

It's about 6 months old. I'm done with it now that I finished my Master's. I could not have gotten through with my statistics courses without this thing!

This baby is going for $100 after tax new in the store and you still have to buy batteries.

How about $70 shipped in USA with batteries installed and ready to go?! $75 outside the USA.

Feel free to propose a trade or counter offer.

Manual and data cable included.

Heh heh. My teacher said...."everything I do in this class that involves a calculator and statitistics will be done on a TI-83+. You can follow along on the examples with any calculator you like but I will be doing it on a TI-83+. The TI-83+ is the best calculator out there for stats, confidence intervals, linear regression and maxtrix manipulation. You can use another calculator if you like but I won't help you trouble-shoot anything."

I got the TI-83 Plus. :mrgrn:

I hate that reverse Polish crap, anyway. :P
 
I have had a TI-85 since 8th grade. Best damn calculator ever. Granted most of the keys don't pop back up on their own, but it still works perfectly for me. The only thing I do with it anymore is simple addition, subtraction, multiplication, and division.

All the college math classes I took didn't allow calculators on tests, which is probably why they were so difficult for me...
 
My HP 15C, bought used in '85, is still on the batteries I installed back in '87. It still works; all the keys and everything. Nothing beats gold contacts. Getting used to RPN took a bit but was defintiely worthwhile.
