What is the Research Methods Knowledge Base?

The Research Methods Knowledge Base is a comprehensive web-based textbook that addresses all of the topics in a typical introductory undergraduate or graduate course in social research methods.  It covers the entire research process including: formulating research questions; sampling (probability and nonprobability); measurement (surveys, scaling, qualitative, unobtrusive); research design (experimental and quasi-experimental); data analysis; and, writing the research paper.  It also addresses the major theoretical and philosophical underpinnings of research including: the idea of validity in research; reliability of measures; and ethics.  The Knowledge Base was designed to be different from the many typical commercially-available research methods texts.  It uses an informal, conversational style to engage both the newcomer and the more experienced student of research.  It is a fully hyperlinked text that can be integrated easily into an existing course structure or used as a sourcebook for the experienced researcher who simply wants to browse.

Using the KB in a Course

Updated editions of the Knowledge Base in printed form (much more sophisticated than this one) are published exclusively by Cengage Publishing (to purchase, see Order the KB). Through Cengage Publishing you can expect the finest in web-based course support for the Knowledge Base including workbooks, study guides, online testing, test item data banks, and much more.

If you are an instructor or faculty member who wants to use part or all of this web version of the Knowledge Base in a course, I ask that yout complete a short request form for each use (course and semester). I will always grant permission for legitimate course use either as a main or supplementary text. I need you to fill out the form partly to satisfy my aggreement with the publisher and mainly to impress my Dean each year when I tell him how important this site is! PLEASE NOTE: If you are a student who is using the Knowledge Base in your coursework or thesis research you do not need to complete this form - you can just use this as long as you cite it appropriately.

Acknowledgements

This work, as is true for all significant efforts in life, is a collaborative achievement. I want to thank especially the students and friends who assisted and supported me in various ways over the years. I especially want to thank Dominic Cirillo who has labored tirelessly over several years on both the web and printed versions of the Knowledge Base and without whom I simply would not have survived. There are also the many graduate Teaching Assistants who helped make the transition to a web-based course and have contributed their efforts and insights to this work and the teaching of research methods.  And, of course, I want to thank all of the students, both undergraduate and graduate, who participated in my courses over the years and used the Knowledge Base in its various incarnations. You have been both my challenge and inspiration.

Dedication

For all of the students who in the end taught me so much more than I could have ever taught them. And to my daughter Nora who continues to provide the inspiration for my efforts.
