Test data were input into an Excel spreadsheet and then exported to WINSTEPS 3.80.1
(Linacre, 2013) and calibrated using the Rasch dichotomous model (Rasch, 1960). The
Rasch model has numerous strengths, such as providing equal interval item and person
measures, item and person fit indices, detailed information concerning item and person
dimensionality, as well as item and person reliability estimates.1
