As a person learning both how to use statistical programs (e.g.: SPSS) and how and when to apply different statistical procedures, this book has been a lifesaver for me. Clearly written, with very helpful step-by-step instructions for running procedures using SPSS's drop down menu, the syntax this creates, and interpretations of output. The authors provide enough theoretical statistical background but not so much that you can't see the forest for the trees. If only all of my time trying to learn statistical procedures had been as well-spent as my time using this guide!
