This text presents a reader-friendly introduction to the basic principles of experimental and non-experimental psychological research. The book is organized so that each chapter focuses on a specific step in the research progress.
This is an excellent book, not only for psychology students but for anybody interested in designing and performing experiments. True, most of the examples are focused on psychologu and pharmacology, but the content can be applied to prett much any other discipline (maybe you can skip the last APA-related chapter).
