This book is designed to help students learn to analyze and interpret research data using intermediate statistics. The new edition features SPSS 12.0 for Windows, but can also be used with versions 10 and 11. Each chapter introduces several related statistics and provides instructions on how to run them and interpret the outputs. The authors describe the use and interpretation of these statistics in user-friendly, non-technical, jargon-free language. The examples use realistic data from the modified high school and beyond (HSB) and college student datasets, available on the CD in the back of the book. The authors' goals are to demonstrate: how to choose the appropriate statistic based on the research design; how to use SPSS to answer research questions; how to interpret SPSS outputs; and how to write about the outputs in the results section of a research paper.
