Notes for the ti-89 calculator

In most TI-89 calculators, you must load a new operating system first and then the APPS statistics program. You can either go to your instructor OR you can go to the TI-89 site to get the operating system and the APPS statistics program. You must go to the TI-89 site to get the Guidebook. It has all the instructions for running the statistics program.

To go to the TI-89 site, click (External Link) to get to the TI-89 link. Then choose "apps" and "Handheld Software Application." From this page, you can download the operating system (version 2.05) and statistics program (Statistics with List Editor - this page will have both the operating system and the program).

You must then load the Advanced Mathematics Software Operating System and the Statistics with List Editor from your computer to the TI-89 calculator (unless your instructor has loaded them directly into your calculator). For that, you will need the TI-GRAPH LINK™ software and the TI-GRAPH LINK™ Cable. TI sells them on their Web Site.
