Evidence for the Validity of a Rasch Model Technique for Identifying Differential Item Functioning
An analysis of differential item functioning (DIF) in a medical specialty certification examination taken by 416 candidates through a simple Rasch model is presented. These analysis results serve as validity evidence for use of the Rasch model as a way to examine DIF in examinations. It is concluded...
