Chapter 3 SPSS^®

We can request visual displays of data from both the “Data View” screen and the “Variable View” screen. SPSS allows us to create visual displays across several different menus; however, most graphing is done in SPSS using the Chart Builder. This section walks you through the general steps to create a graph, using a scatterplot as an example. But first, enter the data in the screenshot for hours spent studying and exam grades that were used to create the scatterplot in Figure 3-5.

Select Graphs → Chart Builder → Gallery. Under “Choose from” select the type of graph by clicking on it. For example, to create a scatterplot, click on “Scatter/Dot.” Drag a sample graph from the right to the large box above. Usually, you’ll want the simplest graph, which tends to be the upper-left sample graph.

Drag the appropriate variables from the “Variables” box to the appropriate places on the sample graph (e.g., “x-axis”). For a scatterplot, drag “hours” to the x-axis and “grade” to the y-axis. Chart Builder then looks like the screenshot shown here. Click OK and SPSS then creates the graph.

Remember: You should not rely on the default choices of the software; you are the designer of the graph. Once the graph is created, you can change its appearance by double-clicking on the graph to open the Chart Editor, the tool that allows you to make changes. Then click or double-click on the particular feature of the graph that you want to modify. Clicking once on part of the graph allows you to make some changes. For example, clicking the label of the y-axis allows you to retype the label; double-clicking allows you to make other changes, such as making the label horizontal (after double-clicking, select the orientation “Horizontal” under “Text Layout”).
