A Model‐Data‐Fit‐Informed Approach to Score Resolution in Performance Assessments

Educational Measurement: Issues and Practice, 2021
AbstractMany large‐scale performance assessments include score resolution procedures for resolving discrepancies in rater judgments. The goal of score resolution is conceptually similar to person fit analyses: To identify students for whom observed scores may not accurately reflect their achievement.

Approaches for Addressing Model-Data Fit

1985
Item response models offer a number of advantages for test score interpretations and reporting of test results, but the advantages will be obtained in practice only when there is a close match between the model selected for use and the test data.

Advancing and Evaluating IRT Model Data Fit Indices in Organizational Research

Organizational Research Methods, 2019
Item response theory (IRT) models have a number of advantages for developing and evaluating scales in organizational research. However, these advantages can be obtained only when the IRT model used to estimate the parameters fits the data well. Therefore, examining IRT model fit is important before drawing conclusions from the data. To test model fit,

Examples of Model-Data Fit Studies

1985
In the previous chapter, a set of steps and techniques were introduced for conducting goodness-of-fit investigations. The purpose of this chapter is to highlight the applications of several of those techniques to the analysis of real data. Specifically, the results of fitting the one- and three-parameter logistic models to four mathematics tests in the

Impedance spectroscopy: Models, data fitting, and analysis

Solid State Ionics, 2005
Abstract First, several impedance spectroscopy models found useful for data fitting and interpretation of dielectric- and conductive-system frequency data are briefly summarized and compared. The first of these are the Kohlrausch KD model for dielectric-system response, representing the frequency response associated with stretched-exponential ...

Fitting IRT Models to Dichotomous and Polytomous Data: Assessing the Relative Model–Data Fit of Ideal Point and Dominance Models

Applied Psychological Measurement, 2011
This study investigated the relative model—data fit of an ideal point item response theory (IRT) model (the generalized graded unfolding model [GGUM]) and dominance IRT models (e.g., the two-parameter logistic model [2PLM] and Samejima’s graded response model [GRM]) to simulated dichotomous and polytomous data generated from each of these models.

Rater fairness in music performance assessment: Evaluating model-data fit and differential rater functioning

Musicae Scientiae, 2015
The purpose of this study was to investigate model-data fit and differential rater functioning in the context of large group music performance assessment using the Many-Facet Rasch Partial Credit Measurement Model. In particular, we sought to identify whether or not expert raters’ ( N = 24) severity was invariant across four school levels (middle ...
