Introducing the Topic

In this chapter, you and your students will learn how to use the Sharp graphing

calculator to find the numerical descriptions of a two-variable data set.

Calculator Operations

Turn the calculator on and press STAT to enter the statistics menu. Touch

A EDIT and press ENTER to access the data entry screen. Delete old data by

highlighting L1 and pressing DEL ENTER . Repeat for other lists.

Enter the following data set:

X Y

25 32

28 33

31 27

40 38

29 30

Please refer to Chapter 5 for discussion on entering a non-weighted two-variable

data set.
