A Comparison on the Rasch Item Probability with Three Common Item Characteristics as Criteria for Item Selection.
Abstract
Selection of items for analogy tests according to the Rasch item probability of 'goodness of fit' to the model is compared with three connonly used item selection criteria: item discrimination, item difficulty, and item-ability correlation. Word, picture, symbol and number analogies in multiple-choice format were administered to several hundred college students. Analysis was made at Rasch item probabilities in terms of proportion of items rejected as criteria was commonly used criteria for item difficulty. Results also showed the amount of overlap among the four criteria.
