u To configure statistical graph settings

1. On the Stat Editor window, tap [SetGraph] - [Setting…] or tap G.

• This displays the Set StatGraphs dialog box. There are tabs named 1

through 9 that correspond to StatGraph1 through StatGraph9.

• Each tab is assigned a color. Tabs [1] and [6]: Blue; Tabs [2] and [7]: Red;

Tabs [3] and [8]: Green; Tabs [4] and [9]: Magenta; Tab [5]: Black

2. Tap the tab for the StatGraph setup whose configuration you want to

change.

3. Configure the StatGraph setup settings you want as described below.

Draw: Select the On setting if you want to draw the tab’s graph, or Off if you

do not want to draw it. After closing the dialog box, tap y on the

toolbar to execute the graph draw operation.

Type: Selects the type of graph to be drawn. The types of graphs available for selection depend on whether

the graph data is single-variable or paired-variable.

Single-variable NPPlot, Histogram, MedBox, NDist, Broken

Paired-variable

Scatter,

xyLine, LinearR, MedMed, QuadR, CubicR, QuartR, LogR,

ExpR, abExpR, PowerR, SinR, LogisticR

For details about each graph type, see “Graphing Single-Variable Statistical Data” (page 131) and

“Graphing Paired-Variable Statistical Data” (page 132).

XList, YList, Freq: Specifies the list data to be used for graphing. If you prepared frequency list data, use

Freq to specify the frequency list.

Mark: This setting is supported only when Scatter,

xyLine, or NPPlot is specified for “Type”. Select square

(q), cross (w), large dot (;) or dot (') as the shape for graph lot points.

4. Tap [Set] to apply the settings for the tab you selected in step 2.

u To draw a statistical graph

1. On the Stat Editor window, tap [SetGraph], and then confirm that there is at least one item from [StatGraph1]

to [StatGraph9] whose check box is selected.

• If no check box is selected, select at least one check box. Selecting multiple check boxes will cause the

corresponding graphs to be drawn simultaneously.

2. Configure the a - [Stat Window Auto] - [On] / [Off] setting as required.

• Selecting [On] for this setting configures View Window settings for drawing statistical graphs automatically.

See “Graph Format Dialog Box” (page 36) for details.

3. Tap y to display the Stat Graph window and draw the statistical graphs.

0701 To input the paired-variable data shown below and then plot the data on a scatter plot

list1 = 0.5, 1.2, 2.4, 4.0, 5.2 list2 = −2.1, 0.3, 1.5, 2.0, 2.4

Graphing Single-Variable Statistical Data

You can produce any of the graphs described below using single-variable data. The text in the parentheses of

the graph names below shows text that appears on the Type menu of the Set StatGraphs dialog box.

Normal Probability Plot (NPPlot)

The normal probability plot plots data against a theoretical normal distribution

using a scatter plot. If the scatter plot is close to a straight line, then the data is

approximately normal. A departure from the straight line indicates a departure

from normality.
