Chapter 4Graphing Data
Section 4.1 Graphing Basics
In addition to the frequency distributions, measures of central tendency, and measures of dispersion discussed in Chapter 3, graphing is a useful way to summarize, organize, and reduce your data. It has been said that a picture is worth a thousand words. In the case of complicated datasets, this is certainly true.
With SPSS, it is possible to make publication-quality graphs. One important advantage of using SPSS to create your graphs instead of using other software (e.g., Excel or SigmaPlot) is that the data have already been entered. Thus, duplication is eliminated, and the chance of making a transcription error is reduced.
