Course Catalog Description:
Virtually all psychological variables are latent, i.e., not directly observable. Consequently, they are measured by observing manifestations of them that are assumed to adequately reflect the underlying latent variables. These observables are typically test questions that have predetermined correct and incorrect options for ability, achievement, and other cognitive variables. For personality, attitudes, and other variables the test questions are based on self report. Two general types of theories are in use for measuring both types of these variables - classical test theory (CTT) and item response theory (IRT). Both theories address measurement issues for both types of variables differently. Taking a practical approach, this course compares both theories in terms of the methods for constructing, refining, scoring, interpretation, applications, and criteria for evaluating the adequacy of measuring instruments developed by both CTT and IRT. Topics include methods of item analysis, special problems of the two types of methods that are unique to the two general types of variables, and special topics including equating, differential item functioning, and multidimensionality. Advantages and limitations of both CTT and IRT will also be discussed.
