The Analysis Of Partial Credit Scoring, Geoff Masters
The Analysis Of Partial Credit Scoring, Geoff Masters
Prof Geoff Masters AO
This article discusses a range of issues in the practical application of an item response theory (IRT) method for partial credit scoring. After a brief discussion of partial credit scoring as an alternative to right-wrong scoring in the measurment of educational achievement, an IRT model for partial credit analysis is developed and described. This model is presented as a straightforward and logical application of Rasch's dichotomous model to a sequence of ordered response alternatives. The distinctive nature of the item parameters in the model is described and these parameters are contrasted with two more familiar sets of parameters: Thurstone thresholds …
Common Person Equating With The Rasch Model, Geoff Masters
Common Person Equating With The Rasch Model, Geoff Masters
Prof Geoff Masters AO
Two procedures, one based on item difficulties, the other based on person abilities, were used to equate 14 forms of a reading comprehension test using the Rasch model. These forms had no items in common. For practical purposes, the two procedures produced equivalent results. An advantage of common person equating for testing the unidimensionality assumption is pointed out, and the need for caution in interpreting tests of common item invariance is stressed.
A Comparison Of Latent Trait And Latent Class Analyses Of Likert-Type Data, Geoff Masters
A Comparison Of Latent Trait And Latent Class Analyses Of Likert-Type Data, Geoff Masters
Prof Geoff Masters AO
This paper brings together and compares two developments in the analysis of Likert attitude scales. The first is the generalization of latent class models to ordered response categories. The second is the introduction of latent trait models with multiplicative parameter structures for the analysis of rating scales. Key similarities and differences between these two methods are described and illustrated by applying a latent trait model and a latent class model to the analysis of a set of 'life satisfaction' data. The way in which the latent trait model defines a unit of measurement, takes into account the order of the …
