Comparison of classical test theory and item response theory in terms of item parameters
There are two currently popular statistical frameworks for addressing measurement problems namely Classical Test Theory (CTT) and Item Response Theory (IRT). This study is aimed empirically to examine the similarities and differences in the parameters estimated using these two frameworks. For this purpose, firstly the model assumptions and the goodness of fit analyses were checked for IRT. The ...

متن کاملLinking Item Response Model Parameters
With a few exceptions, the problem of linking item response model parameters from different item calibrations has been conceptualized as an instance of the problem of test equating scores on different test forms. This paper argues, however, that the use of item response models does not require any test score equating. Instead, it involves the necessity of parameter linking due to a fundamental ...
متن کاملROC parameters in item and context recognition.
Conflicting theories argue that recognition is achieved either by familiarity exclusively, or by a mixture of familiarity and recollection. We explore in three experiments the goodness of fit of both positions to experimental data in which context information is manipulated. In Experiments 1 and 2, we explore the availability of context information in recognition, testing the focus stimulus, it...
