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<I> and</I> 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.
