Publisher Synopsis

"Although there are a number of software programs available for power analysis, this volume teaches the reader how to employ power analysis using a popular software program (R) that can also be used to perform the desired statistical analyses on the data." -- Leslie Echols "Introduction to Power Analysis provides detailed coverage of the topic in a succinct and concise way.
