Scott E. Maxwell is the Fitzsimons Professor of Psychology at the University of Notre Dame. His research interests are in the areas of research methodology and applied behavioral statistics, with much of his recent work focusing on statistical power and accuracy in parameter estimation, especially in randomized designs. Professor Maxwell has served as editor of Psychological Methods, received the Samuel J. Messick Award for Distinguished Scientific Contributions by the American Psychological Association's Division of Evaluation, Measurement, & Statistics, and has received multiple teaching awards.

Harold D. Delaney is Emeritus Professor of Psychology at the University of New Mexico, where he received the University's Outstanding Graduate Teacher of the Year award. His research interests in applied statistics include methods that accommodate individual differences among people. Professor Delaney received a Fulbright Award from the U.S. Department of State to spend an academic year lecturing in Budapest, Hungary.

Ken Kelley is Professor of Information Technology, Analytics, and Operations (ITAO) and the Associate Dean for Faculty and Research in the Mendoza College of Business at the University of Notre Dame.
