This is a guide to some of the more commonly ud functions needed for the AP Statistics curriculum in the Statistics with List Editor Application for the TI-89/TI-92 Plus, hereinafter referred to as Stats/List Editor. As far as I can tell the statistics package in the Stats/List Editor is in every way superior to the statistics package that comes in the TI-89. So the statistics package that comes in the TI-89 need never be studied.
The TI-83 Plus was designed (veral years ago) with a very extensive statistics package and is currently the calculator of choice for most AP Statistics class. Stats/List Editor installs this extensive statistics package in a TI-89. Becau the ur interface on the TI-89 is superior to that of the TI-83 Plus and becau the TI-89 is more powerful and enjoyable t
o u than the TI-83 Plus and becau the TI-89 does things that the TI-83 does not do (such as, multiple regression, one and two-way analysis of variance), I strongly recommend statistics students buy a TI-89, not a TI-83 Plus.
Stats/List Editor is available as a free upgrade from TI at /calc/flash/89.htm. You can also download the free 200-page manual. To install this upgrade you need to first install the Advanced Mathematics Software Operating System Version 2.05 (AMS 2.05) [or whatever is the current version] available as a free upgrade from TI at /calc/flash/89ams.htm. Both of the above can be installed only if you have the TI GraphLink software (available free at /calc/docs/link.htm) on your computer and a gray or black TI GraphLink cable (about $30 - See the dealer list at the GraphLink site.) to transfer it to your TI-89.
Page numbers listed below refer to the page in the Statistics with List Editor Application manual 1999 Texas Instruments. There is little contained herein that is not said better in the official manual, but this guide, hopefully, is be a bit more focusd and less imposing t
han the 200 page guide.

Random Number Generators p. 103
A random number generator produces numbers in such a way that every number in the range has an equal possibility of being produced. F4 Calc 4: Probability has ven different kinds of random number generators.
Note that in EXACT mode none of the random number functions work right. For instance, randint(0,10,5) gave me {-1.,-1.,-1.,-1.,-1.) and rand83(3) gave me {0, 0, }. So u AUTO mode.
rand83( F4 Calc 4: Probability 1: rand83(n) generates a list of n random real numbers, x, such that 0 < x < 1. Move the cursor to the name of a list that you want to fill with random numbers and key rand83(n). E.g. rand83(3) put .73381, .04399 and .33936 in a list. Actually each number had 14 digits, but the format was t to display only five digits.
