Abhik Roy, Kristin Hobson, and Chris Coryn on the Scriven Number

Hi, we’re Abhik Roy and Kristin A. Hobson, students and Doctoral Associates (we know what you’re thinking…wow…they must be rich) in the Interdisciplinary Ph.D. in Evaluation (IDPE) at Western Michigan University (WMU), and Dr. Chris L. S. Coryn, Professor of Evaluation, Measurement, and Research and Director of the IDPE (our boss…please tell him to pay us more). Recently, Abhik formulized a Scriven number and we wrote a paper on it entitled “What’s in a Scriven Number?”

Lesson Learned: What’s so important about a Scriven number? Since the article appeared, evaluators are asking each other “what’s your Scriven number?” Perhaps you’re new to the field of evaluation and have no idea what this means or the significance. Dr. Michael Scriven is widely considered the father of modern evaluation. His influence theoretically and in application within the field of evaluation has ben quite significant as his numerous manuscripts total over 400. In addition, Dr. Scriven is a past president of the American Educational Research Association and the American Evaluation Association. He is also an editor and co-founder of the Journal of MultiDisciplinary Evaluation.

Cool Trick: Determining your Scriven number. You may be asking, what’s a Scriven number? Well that’s what we’re here to explain. To put it simply, a Scriven number is a measure of collaborative distance, using both direct and indirect authorship, a person is from Dr. Scriven. Ok maybe that wasn’t so simple. Let’s try explaining this in a different way. A Scriven number is how far you, as an author of a published paper, are away from Dr. Scriven. In other words, Dr. Scriven has a Scriven number of zero, a person who has written a paper with Dr. Scriven has a Scriven number of one, a person who has written a paper with another person who wrote a paper with Dr. Scriven has a Scriven number of two, and so on. For example, using the paper Cook, Scriven, Coryn, and Evergreen (2010), Cook, Coryn, and Evergreen have a Scriven number of one. Now anyone who has published with Cook, Coryn, or Evergreen receives a Scriven number of two, unless the person has published with Dr. Scriven directly, then the person has a Scriven number of one. If a person has multiple Scriven numbers, his or her Scriven number is the lower number.

    SO, A Scriven number only applies to Dr. Scriven and individuals that have co-authored or authored with said “co”? How does this unit of measurement apply to Theories of Evaluation. I don’t understand the practicality of the Scriven number or its application. As a co-author say your scriven number is 5, does that mean anything really other than you have done no direct work with Dr. Scriven? What happens if I get my Phd. and Dr. Scriven co-authors me; what does that do to the number evaluation for both of us by your standard?
