Advantages to Using the TI-83, TI-83 Plus, and TI-84 Plus
This calculator manual will focus on how to get the most out of using the TI-83, TI-83 Plus, and
the TI-84 Plus calculators by Texas Instruments. The TI-83 was first released in 1996, improving
upon its predecessors the TI-81 and TI-82 with the addition of many advanced statistical and
financial functions. The TI-83 Plus and the TI-84 Plus have essentially the same features as the
TI-83, but with increased memory capacity and a few extra statistical features. They are powerful
calculators with advanced functions, but at the same time easy to use.
• Most complicated statistical computations are handled through menus which prompt
you for the necessary input.
• Data entry and revision is handled through a Stat List Editor that is similar to a
spreadsheet in how it is used.
• Statistical graphs are handled through menus and important parts of the graph can be
read by tracing along with the arrow keys.
• The calculators are built sturdily, and can withstand many falls off of student desks.
Entering and Revising Data
This chapter focuses on getting numbers into your calculator and storing them for the
organization, interpretation, and analysis part of statistics. When you are not given the necessary
statistics to perform calculations, you will need to enter data into the calculator to generate the
statistics. We will learn how to do statistical calculations with the calculator in future chapters.
Using the Stat List Editor
The Stat List Editor in the TI-83, TI-83 Plus, and TI-84 Plus calculators provides a convenient
way to enter numbers and review them. Numbers from a data set can be stored in a list in the
calculator so that we can keep numbers that are related to each other together.
Example: Weights
Suppose that you have ten people in a room, with the following weights in pounds:
131, 114, 167, 180, 126, 134, 188, 175, 133, 130
If we want to do any sort of analysis on these numbers, we will need to get them into the
calculator and keep them together as a group.
