This book demonstrates the application of power analysis to the newer more advanced techniques such as hierarchical linear modeling, meta-analysis, and structural equation modeling used in behavioral and social science research. It reviews both basic and advanced designs. Examples demonstrate power analysis through the use of R, SAS, and SPSS and show readers how to produce power tables when preparing a grant proposal. The corresponding computer code is available on the book's website along with a user guide and additional worked examples. The chapters closely parallel the coverage of graduate courses on research methodology/design making this an ideal supplement for such courses.
