Background
Biography
Andrew F. Hayes is a quantitative methodologist and holds a PhD in Psychology from Cornell University as well as a BA in Psychology from San Jose State University. He is a Distinguished Research Professor in the Organizational Behavior and Human Resources area of the Haskayne School of Business and the director of the Canadian Centre for Research Analysis and Methods housed at the University of Calgary. His research and writing on applied statistical methods has been published in such journals as Psychological Methods, Multivariate Behavioral Research, Behavior Research Methods, British Journal of Mathematical and Statistical Psychology, Psychological Science, Journal of Educational and Behavioral Statistics, American Behavioral Scientist, Communication Monographs, Journal of Communication, and Australasian Marketing Journal, among many others.
He is the author of Introduction to Mediation, Moderation, and Conditional Process Analysis (2022) and Regression Analysis and Linear Models (2017), both published by The Guilford Press, and Statistical Methods for Communication Science (2005), published by Routledge. He also invented the PROCESS macro for SPSS, SAS, and R (processmacro.org), widely used by researchers examining the mechanisms and contingencies of effects. He teaches courses on applied data analysis and also conducts online and in-person workshops on statistical analysis to multidisciplinary audiences throughout the world, most frequently to faculty and graduate students in business schools but also in education, psychology, social work, communication, public health, and researchers in government. His work has been cited over 230,000 times according to Google Scholar, and he has been designated a Highly Cited Researcher by Clarivate Analytics in 2019, 2020, 2021, 2022, and 2023.
