New book from Appraisal Institute guides through statistical analyses

Sep 22, 2009

A newly published textbook by Marvin L. Wolverton, Ph.D., MAI, is the first of its kind: a fundamental, comprehensive guide to performing statistical analyses written specifically for real estate appraisers. Published this month by the Appraisal Institute, the nation’s largest organization of real estate appraisers, An Introduction to Statistics for Appraisers makes its debut as appraisers face increasing pressure to support their opinions of value. Amidst new educational criteria requiring demonstrated proficiency in basic statistics, appraisers find themselves needing to learn even more about statistics and modeling. An Introduction to Statistics for Appraisers includes a review of essential mathematical skills; advice on illustrating data graphically; instruction on the concept of probability and its application in statistical analysis; sophisticated tools for testing research and assessing the validity and reliability of data samples; and information on statistical model building using simple and multiple linear regression. Marvin L. Wolverton, Ph.D., MAI, is a practicing real property valuation theorist and consultant currently employed as a senior director in the national Dispute Analysis and Litigation Support practice at Cushman & Wakefield, where he engages in litigation consulting and expert witness services. He resides in Leander, Texas. He is a professor emeritus and former distinguished professor of real estate at Washington State University who has authored dozens of articles for academic and professional journals and real estate practitioner publications. Dr. Wolverton served five years as senior editor of the Journal of Real Estate Practice and Education and has served on the editorial boards of the Journal of Real Estate Research and The Appraisal Journal. He also teaches a limited number of pre-licensing and continuing education courses for the Appraisal Institute. For more information, visit
