This user-friendly text guides the novice user through the process of entering and analyzing data using Versions 8, 9, and 10 of SPSS. The text: * assumes only the most basic knowledge of Windows; * reminds students of basic issues regarding design and statistics; * proceeds gently through the major quantitative statistical techniques used in psychology; * introduces students to the rationale and use of each test; and * provides clearly annotated examples of SPSS output. In this way, users are shown how to choose, perform, and report the statistical analysis of their own data. The emphasis the text places on considering what the output from SPSS means is a result of the authors' realization that students need to understand that using SPSS and understanding the output of SPSS are two different things.
