I purchased this book to use with a grad class in multiple regression, where the syllabus follows the book closely. I don't know how easy-to-use the book would be without a supporting class, but in class and doing homework, it is extremely helpful. Carefully and plainly explains every aspect of multiple regression. Leaves out or segregates (in "black box" explanations) the complicated math that the computers do for us.This book does NOT include steps for using SPSS or any other stats package, but acknowledges you will be using a computer for calculation. All the better in my opinion, as it won't become obsolete after the next major software revision.This text is often cited when using multiple regression in a published study.
