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.
