This book is organized into 3 general categories: the research process and how data that has been collected can be organized, presented and summarized (chapters 1 - 4); the process of conducting statistical analyses to test research questions, and hypotheses and issues and controversies regarding the process (chapters 5 - 10) and the last section which examines statistical procedures used in research situations that vary in the number of independent variables in the study, as well as how the independent and dependent variables have been measured (chapters 11 - 14). Every chapter contains learning checks which include review questions, and exercises are included at the end of every chapter to help assess what was learned.
Howard T. Tokunaga is a professor of psychology at San Jose State University, where he serves as coordinator of the MS Program in Industrial/Organizational (I/O) Psychology and teaches undergraduate and graduate courses in statistics, research methods, and I/O psychology. He received his bachelor's degree in psychology at UC Santa Cruz and his PhD in psychology at UC Berkeley. In addition to his teaching, he has consulted with a number of public sector and private sector organizations on a wide variety of management and human resource issues. He is co-author (with G.
