Buy a TI-84+ (or a calculator from the TI-84+ line or calculators, including the TI-83+, TI-84+, TI-84+ silver edition, TI-Nspire or TI-Nspire CAS) calculator. A calculator from the TI-84+ line of calculators is an integral part of the course. It is used very heavily throughout the course. You will be at a disadvantage if you do not purchase this calculator.
You can use any calculator you want, but be forewarned the course (Attendance Workbook, homework assignments and quizzes) is designed for the TI-84+ (and only the TI-84+) line of calculators. I support the TI-84+ line of calculators only.
Buy a calculator from the TI-84+ line of calculators only.
Check out the TI-84+ video tutorials.
The courses listed below use programs I have created for the TI-84+ line of calculators only. If you are a class student, I will distribute the programs during class time. If you are a local internet student, drop by my office so that I can load these programs onto your calculator. If you are a distance learning student, buy the cable to connect your computer to your calculator, to allow you to take these programs from this web site and install them on your calculator. Do this immediately, at the beginning of the semester. Previous students have commented how time consuming this is to do. Do not wait until half way through the semester to load these programs onto your calculator!

A special cable that connects your calculator to your computer, called a TI-Graph Link, can access these programs. These cables are available at most computer or office supply stores. In addition, you must install special software on your computer that instructs your computer on how to talk to your calculator through the TI-Graph Link cable.

Other calculators are not supported. Although the operating system of a TI-86 (TI-89, TI-89 Titanium, TI-92, Voyage 200 and any other calculator which is not in the TI-84+ line of calculators) can be altered somewhat to have "similar" statistical capabilities as the TI-84+ line of calculators, these other calculators are simply too different from the TI-84+ line of calculators to be useful for homework assignments, quizzes or any other classroom activity requiring their use. In particular, there are list-like functions in a TI-86, but they are so different than the lists in the TI-84+ line of calculators, they are very difficult to use in any meaningful way. The important programs written for the TI-84+ line of calculators for the courses I teach cannot be run on any other line of calculators. Students who use a TI-86 (TI-89, TI-89 Titanium, TI-92, Voyage 200 and so on) calculators will be at a serious disadvantage to students who use a calculator from the TI-84+ line of calculators.
