Comparison Of Four Models For Predicting Person Reliability
… reliability, which was defined as across-session item consistency. Two prediction models were based on item characteristics alone, namely, p-values and social desirability scale values. Two prediction models attempted to take into account both item and person characteristics. These models were …

An empirical investigation of the robustness of the Mantel-Haenszel procedure and sources of differential item functioning
… procedure used to appraise differential item functioning or item bias and to investigate item characteristics which results in differential performance for the gender and ethnicity comparison.

Comparing 12 finite state models of examinee performance on multiple-choice tests
… finite state modeling, various assumptions about item characteristics and the examinees’ response strategies are made to estimate an examinee ability, and willingness to guess. Twelve sets of plausible assumptions about identifiability of distractors and examinee guessing strategies were adopted …

The Relationship of Passage Independent and Passage Dependent Test Items to Each Other and to Cultural Item Bias
… of pre-specified standardized achievement test item characteristics to culturally related item bias. The relative passage or context independence of certain reading comprehension items was hypothesized to be a potential source of such bias in an example test, the Science Research Associates …

Using Appropriateness Measurement to Detect Realistic Faking of Personality Tests
… examining how well a pattern of responses fit item characteristics) has not been thoroughly investigated. The present study examines whether the two most popular appropriateness indices, Z3 and F2, are capable of detecting response distortion among test takers instructed to answer honestly …

Toward effective common operating policies for medical items in ongoing humanitarian operations : the science and art of segmentation : a case study
… operations can suffer from the lack of medical item availability. The central problem thus becomes how to ensure the right item in the right place at the right time while maintaining appropriate costs. By means of a case study, this research grouped items by various item characteristics and …

Race, gender and omissions on standard achievement tests
… graders in the Commonwealth of Virginia. Item characteristics (difficulty, discrimination and an index of differential item functioning) were used as independent variables in regression equations for the male/female case and the black/white case. In both cases item difficulty was the only …

Conspiracy Theory: An Empirical Study of Cheating in a Continuous Testing Environment
The effect of item characteristics on examinee recall of test items is examined in the paper. Study One evaluated item length, difficulty, guessing, discrimination, serial position, misfit, format, memoriability, clarity, familiarity, interest, and examinee ability as predictors of item recall. …

The general cognitive ability of Maori and European subjects: a comparative study of Queensland test performances and psychometric properties
… data. Queensland Test reliability, validity and item characteristics were researched for the two ethnic groups. To obtain test-retest reliability estimates and data on criterion related validity longitudinal studies were undertaken with four ethnically mixed class groups Standard 3 to Form 2). …

The Relationship Between Rater Agreement, Behavioral Observability and Overall Impressions
<p>This study examined two item characteristics believed to influence rater agreement: observability and difficulty. The first goal of this study was to replicate the findings of Roch, Paquin and Littlejohn (2009), which found that rater agreement was negatively related to item observability …

Similarity learning in the era of big data
… challenges brought by the inherent “three-Vs” characteristics of big data by answering the following questions: 1) Similarity is characterized by both links and node contents in networks; how to identify the contribution of each network component to seamlessly construct an application …

Further Evaluating the Effect of Behavioral Observability and Overall Impressions on Rater Agreement: A Replication Study
… that raters are more likely to agree when items are either more difficult to rate or less observable. In the replication study conducted by Scott, the results did not support the relationship which Roch et al. found between observability and rater agreement, but did support the relationship …
