"Sage's 'little green books' have been my 'go to' source for quick and easy introductions to statistical methods for over 25 years. From Cluster Analysis and Factor Analysis to Multiple Comparisons and Bootstrapping (some of my favorites!), Sage's little green books are always clear, uncluttered, and practical. Happy anniversary QASS series!"
