Statistical Methods Seminar Description
Overview: Psychometrics is defined as the science of evaluating the characteristics of tests or other devices designed to measure psychological attributes of people. Tests are broadly defined as devices for measuring ability, aptitude, achievement, attitudes, interests, personality, cognitive functioning, and mental health. Application of psychometrics to psychology and social/behavioral science constitutes an organized effort to (a) develop and test theory-based measurement procedures for the development of tests and other measurement instruments/devices and (b) advance knowledge in psychological and sensory processes. Topics covered in this seminar include (a) measurement and statistical concepts, (b) scaling, (c) validity, (d) reliability, (e) factor analysis, (f) measurement invariance, including item and test bias and the role each plays in test fairness, (g) introduction to item response theory, (h) introduction to generalizabilty theory, (i) survey of advanced topics in psychometrics, and (j) developing norms and conducting test score equating.

Instructors: Larry Price, Ph.D. & Todd D. Little, Ph.D.
Larry is Professor of Psychometrics & Statistics and Director of the Initiative for Interdisciplinary Research design and Analysis (IIRDA) at Texas State University. Prior to joining Texas State University, he served as a Psychometrician and Statistician for the Emory University School Medicine, Department of Psychiatry & Behavioral Sciences from 1993 to 1999. Between 1999 and 2001, Dr. Price was employed at The Psychological Corporation in San Antonio, Texas as a Psychometrician/ Statistician II where he worked on the Wechsler Scales of Intelligence and Memory and other test of cognition, achievement and neuropsychology. In his role as Director of IIRDA, Dr. Price collaborates with interdisciplinary teams in conceptualizing and writing the analytic segments of largescale competitive proposals for National Institutes of Health, Institute of Education Sciences, National Science Foundation (CAREER and STEM), and Department of Defense.
Larry has a new book titled Psychometric Methods: Theory into Practice published by Guilford, June 2016.
Todd D. Little, PhD is a Professor and director of the Institute for Measurement, Methodology, Analysis and Policy at Texas Tech University. He is widely recognized for his quantitative work on various aspects of applied SEM (e.g., modern missing data treatments, indicator selection, parceling, modeling developmental processes) as well as his substantive developmental research (e.g., action-control processes and motivation, coping, and self-regulation). His work has garnered over 26,794 citations with an h-index of 81 and an i10-index of 186. In 2001, he was elected to membership in the Society for Multivariate Experimental Psychology, and in 2009, he was elected President of APA’s Division 5 (Evaluation, Measurement, and Statistics). He is a fellow in APA, APS, and AAAS. In 2013, he received the Cohen award from Division 5 of APA for distinguished contributions to teaching and mentoring and in 2015 he received the inaugural distinguished contributions award for mentoring developmental scientists from the Society for Research in Child Development. Both awards cited his founding of Stats Camp (Statscamp.org) in 2003 and its ongoing impact on shaping the quality of scientific inquiry for both past and future generations of researchers.
