Each dot’s position on the X (horizontal) axis represents a student’s mid-term exam score, and its position on the Y (vertical) axis represents their final exam score.Īfter we create a scatter plot, we need to review it to assess the nature of the relationship – if any – that exists between our variables. The SPSS Output Viewer will pop up with the scatter plot that you’ve created.Įach student in our hypothetical study is represented by one dot on our scatter plot. Select “OK” to generate your scatter plot. To do this, click the “Titles” button, add your title, and click “Continue” to return to the “Simple Scatterplot” dialog box. It is a good idea to give your scatter plot a title.
In these cases, it doesn’t matter which variable you move to the “X Axis” box and which variable you move to the “Y Axis” box. If your data is from a simple correlation study, as is the case with our example, there may not be obvious predictor/independent and criterion/dependent variables. If your data is from a regression study, select your predictor/independent variable, and use the arrow button to move it to the “X Axis.” Then select the criterion/dependent variable, and use the arrow button to move it to the “Y Axis” box. The next step is to move your variables into the “X Axis” and “Y Axis” boxes. We recommend that you click the “Reset” button to clear any previous settings. This brings up the “Simple Scatterplot” dialog box below. Select “Simple Scatter” and then click “Define.” This brings up the Scatter/Dot dialog box: Create a Scatter PlotĬlick Graphs -> Legacy Dialogs -> Scatter/Dot as illustrated below: We want to create a scatter plot to visualize the relationship between the two sets of scores. This hypothetical data set contains the mid-term and final exam scores of 40 students in a Statistics course (the first 20 records are displayed above). (Check out our tutorials on importing data from Excel or MySQL into SPSS). The starting assumption for this tutorial is that you have already imported your data into SPSS, and that you’re looking at something like the data set below. Ensure that “Linear” is selected under “Fit Method”.Double-click on your scatter plot to open the “Chart Editor”.Your scatter plot will appear in SPSS Output Viewer.Select “Titles” to add a title (recommended).Select the criterion/dependent variable and move it into the “Y Axis” box.Select the predictor/independent variable and move it into the “X Axis” box.Click Graphs -> Legacy Dialogs -> Scatter/Dot.
