"The measurement chapters are very well done....I think [this book is] excellent."—Contemporary Psychology"A true asset of the book, and a marvelous resource for students and researchers alike, is the extensive citation of relevant references to guide the reader in acquiring additional knowledge on selected topics....an exceptionally readable book, with much to offer as a text for an introductory graduate sequence in research methods and statistics."—Journal of the American Statistical Association"...the richness of each topical discussion allows exploration in several directions and in depth with the goal of interpreting data (wherever they are found) in an intelligent thoughtful manner. Excellent! It belongs on one's desk within arm's length."—Perceptual and Motor Skills"...a good and very useful book to have, not in the least because it makes explicit so many obvious but often neglected issues in doing research....a helpful companion for scientists intent on improving their research and assessing the research of others."—Psychologica Belgica
