Natalie Koziol, a CYFS graduate student affiliate in educational psychology, recently received the 2010-2011 Folsom Distinguished Master’s Thesis Award. The award recognizes distinguished scholarship and research at the master’s level.
Koziol’s thesis is titled “Evaluating Measurement Invariance with Censored Ordinal Data: A Monte Carlo Comparison of Alternative Model Estimators and Scales of Measurement.” In it, Koziol addresses the statistical testing of measurement invariance, which assumes that a scale measures the same construct when used across time or groups. She specifically evaluates how several factors, including sample size and the non-normality of data, influence the validity of statistical conclusions. She also examines how the effects of these factors vary according to measurement models and estimators.
