"The fourth edition of Research Methods for the Behavioral Sciences uses a problem-focused approach to introduce research methods in a way that fully integrates the decision tree-from identifying a research question to choosing an appropriate analysis and sharing results. This book begins with an introduction to the general research process, ethics, identifying and measuring variables, conducting literature reviews, selecting participants, and more. Research designs are then introduced in a logical order, from the least controlled (nonexperiments and quasi-experiments) to the most controlled (experiments). Throughout each chapter, students are shown how to structure a study to answer a research question (design) and are guided through the challenging process of choosing an appropriate analysis or statistic to make a decision (analysis). This book integrates statistics with methods in a way that applies the decision tree throughout the book and shows students how statistics and methods fit together to allow researchers to test hypotheses using the scientific method. The following are unique features in this book to facilitate student learning:"-- Provided by publisher.
