Quantitative psychology is the science of developing and evaluating methods and statistical models for the purposes of measuring and understanding human behavior.

The birth of quantitative psychology has been motivated by the need to solve problems in psychology with the application of applied mathematics overlapping with statistics. Areas of research include psychometrics, mathematical psychology, research design, mediation models, latent variable models, multilevel models, longitudinal data analysis, graphical analysis, Bayesian analysis, decision models, and other related methods.

Our quantitative program has a long and distinguished history. Numerous internationally prominent quantitative and mathematical psychologists have been on the faculty  of Ohio State such as Robert C. MacCallum, Barbara Mellers, Elke Weber, Michael W. Browne,  Jay Myung, Hal Arkes, and Robert C. Cudeck. A brief history of our program and the faculty who contributed to this narrative can be found here.

Many graduates of the quantitative psychology program have gone on to be highly successful in their academic and non-academic careers. Distinguished academics include Guangjian Zhang, Kristopher J. Preacher, Ed Merkle, Hao Wu, and Brandon Turner. Prominent non-academics are Tateneni Krishna, Longjuan Liang, and Xu Nu. A list of many of our graduates can be found here.
