Chapter 7 Statistical Graphs and Calculations

k Plotting a Scatter Diagram

It is often difficult to spot the relationship between two sets of data (such as height

and shoe size) by simply looking at the numbers. Such relationships often become

clear however, when we plot the data on a graph, using one set as

x-values and the

other set as y-values.

uTo plot a scatter diagram

Example To plot the data we input in statistical data List 1 and List 2

1(GPH1)

• The default setting automatically uses List 1 data as x-axis values and List 2 data

as y-axis values. Each set of x/y data is a point on the scatter diagram.

•To return to the statistical data list, press Q.

k Changing Graph Parameters

Use the following procedures to specify the graph draw/non-draw status, the graph

type, and other general settings for each of the graphs in the graph menu (GPH1,

GPH2, GPH3).

1. Graph draw/non-draw status (SELECT)

The following procedure can be used to specify the draw (On)/non-draw (Off) status

of each of the graphs in the graph menu.

uTo specify the draw/non-draw status of a graph

1. While the graph menu is on the display, press [1 (SEL) to display the graph

On/Off screen.

1(GRPH)

[1(SEL)

1 (On) .......... Graph On (graph draw)

2 (Off) .......... Graph Off (graph non-draw)

4 (DRAW) .... Draw all On graphs

•Note that the S-Grph1 setting is for Graph 1 (GPH1 of the graph menu), S-Grph2

is for Graph 2, and S-Grph3 is for Graph 3.
