Using nontechnical, jargon-free language, Leech (University of Colorado) demonstrates how to produce a variety of statistics that are usually included in intermediate statistics courses, plus some that are useful for doing research, in this supplemental text/CD-ROM package for an intermediate statistics course in the behavioral sciences or education. This second edition contains new material on subjects including effect size, assumptions, and exploratory factor analysis. The CD-ROM contains real data files for use with exercises. Students need access to SPSS to use the text.
