2 Chapter 0 – Introduction to TI Calculators
0.1 Key Differences Between Models
All calculators in the TI-83/84/89 series have built-in statistical capabilities. Although a few
statistical functions are "native" on the TI-89, most of the topics covered in a normal Statistics
course require downloading the Texas Instruments Statistics with List Editor application which is
free. Download requires the TI-Connect cable. See the web page
http://education.ti.com/us/product/tech/89/apps/appslist.html
assumes the statistics application has been loaded on the calculator. If you have the newer TI-89
Titanium edition, the statistics application comes pre-loaded, and the TI-Connect cable is
included with the calculator.
The TI-83 and -84 series calculators are essentially keystroke-for-keystroke compatible;
however, the 84 does have some additional capabilities (some additional statistical distributions
and tests, for example) with the latest version of the operating system, version 2.41 which is also
available for download at education.ti.com.
There are some major differences in calculator operation and menu systems which will, in some
cases necessitate separate discussions of procedures for the TI-83/84 and TI-89 calculators.
Some of these will become apparent in the next section. Not only are there differences between
the three series, but there is also a difference in operation between the TI-89 and the TI-89
Titanium edition. On the Titanium, all "functions" on the calculator are essentially applications
– when a regular TI-89 is turned on, the user is on the "home screen" similar to that for the TI-83
and -84. When the Titanium edition is first turned on, one must scroll using the arrow keys to
locate the desired application – we'll say more about this later.
0.2 Keyboard and Notation
All TI keyboards have 5 columns and 10 rows of keys. This may seem like a lot, but the best way
to familiarize yourself with the keyboard is to actually work with the calculator and learn out of
necessity. The keyboard layout is identical on the 83+ and 84+. The layout of the 89 (and 89
Titanium) keyboard is similar, but some functions have been relocated. You will find the
following keys among the most useful and thus they are found in prominent positions on the
keyboard.
The cursor control keys |, ~, } and † are located toward the upper right of your
-
keyboard. These keys allow you to move the cursor on your screen in the direction which
the arrow indicates.
The o key is the leftmost key on the top row of 83 and 84 keyboards. It is utilized more
-
in other types of mathematics courses (such as algebra) than in a statistics course;
however you will use the 2 function above it quite often. This is the STAT PLOT
menu on the -83/84 series. We will discuss 2 functions shortly. On TI-89 calculators,
the Y= application is accessed by pressing ¥ƒ. The STAT PLOT menu on the TI-89
series is found inside the Statistics application.
The É key is in the bottom left of the keyboard. Its function is self-explanatory. To
-
turn the calculator off, press 2É.
