One common modification to the Angoff standard-setting method is to have panelists round their ratings to the nearest 0.05 or 0.10 instead of 0.01. Several reasons have been offered as to why it may make sense to have panelists round their ratings to the nearest 0.05 or 0.10. In this article, we examine one reason that has been suggested, which is…

This study investigates the relationships among factor correlations, inter-item correlations, and the reliability estimates of subscores, providing a guideline with respect to psychometric properties of useful subscores. In addition, it compares subscore estimation methods with respect to reliability and distinctness. The subscore estimation…

In theory the formula scoring methods increase the reliability of multiple-choice tests in comparison with number-right scoring. This study aimed to evaluate the impact of the formula scoring method in clinical anatomy multiple-choice examinations, and to compare it with that from the number-right scoring method, hoping to achieve an…

Students in a junior- and senior-level Anatomy and Physiology course have the opportunity to correct missed exam questions ("regrade") and earn up to half of the original points missed. The three objectives of this study were to determine if: (a) performance on the regrade assignment was correlated with scores on subsequent exams, (b)…

We used meta-analysis to examine the criterion validity of four scoring procedures used in curriculum-based measurement of written language. A total of 22 articles representing 21 studies (N = 21) met the inclusion criteria. Results indicated that two scoring procedures, correct word sequences and correct minus incorrect sequences, have acceptable…

Bloom's taxonomy was adopted to create a subject-specific scoring tool for histology multiple-choice questions (MCQs). This Bloom's Taxonomy Histology Tool (BTHT) was used to analyze teacher- and student-generated quiz and examination questions from a graduate level histology course. Multiple-choice questions using histological images were…

Studies based on longitudinal data focus on the change and development of the situation being investigated and allow for examining cases regarding education, individual development, cultural change, and socioeconomic improvement in time. However, as these studies require taking repeated measures in different time periods, they may include various…

In recent years, the social sciences have seen a resurgence in the study of divergent thinking (DT) measures. However, many of these recent advances have focused on abstract, decontextualized DT tasks (e.g., list as many things as you can think of that have wheels). This study provides a new perspective by exploring the reliability and validity…

Critics of testing for admission purposes cite the moderate correlations of admissions test scores with success in college. In response, this study applies formulas from classical measurement theory to observed correlations to correct for restricted variances in predictor and success variables. Estimates of the correlations in the population of…

To rule out the need for a two-parameter item response theory (IRT) model during item analysis by Rasch models, it is important to check the Rasch model's assumption that all items have the same item discrimination. Biserial and polyserial correlation coefficients measuring the association between items and restscores are often used in an informal…

Automated scoring models for the "e-rater"® scoring engine were built and evaluated for the "GRE"® argument and issue-writing tasks. Prompt-specific, generic, and generic with prompt-specific intercept scoring models were built and evaluation statistics such as weighted kappas, Pearson correlations, standardized difference in…

In educational testing, subscores may be provided based on a portion of the items from a larger test. One consideration in evaluation of such subscores is their ability to predict a criterion score. Two limitations on prediction exist. The first, which is well known, is that the coefficient of determination for linear prediction of the criterion…

The purpose of this note is to derive a simple formula which gives the correlation between shortened versions of two tests, based on the correlations between the longer tests. (Author)

Results of this study suggest that children (ages 6-16) with a sufficient number of emotional indicators (three or more) to create a suspicion of emotional disturbance do not recall significantly fewer Bender designs than do children whose indicators fall within normal limits. (Author/SJL)

The reliabilities yielded by several differential option weighting scoring procedures were compared among themselves as well as against conventional testing. It was found that increases in reliability due to differential option weighting were a function of inter-item correlations. Suggestions for the implementation of differential option weighting…
