Background/Context: Pass/fail standardized exams frequently selectively rescore failing exams and retest failing examinees. This practice distorts the test score distribution and can confuse those who do analysis on these distributions. In 2011, the Wall Street Journal showed large discontinuities in the New York City Regent test score…

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…

The surgical theatre educational environment measures STEEM, OREEM and mini-STEEM for students (student-STEEM) comprise an up to now disregarded systematic overestimation (OE) due to inaccurate percentage calculation. The aim of the present study was to investigate the magnitude of and suggest a correction for this systematic bias. After an…

Scores are the most visible and widely used products of a testing program. The choice of score scale has implications for test specifications, equating, and test reliability and validity, as well as for test interpretation. At the same time, the score scale should be viewed as infrastructure likely to require repair at some point. In this report…

Using parameter estimates the computer program calculates the negative hypergeometric distribution and computes the classification proportions: suitable-accepted, suitable-not accepted, not suitable-accepted, and not suitable-not accepted. (RC)

Results obtained by the Kudar-Richardson formula (20) adapted for use with R-KW scoring are compared with three other reliability formulas. Based on parallel tests administered at the same sitting the KR (20) estimates are compared with alternate-form correlations and with odd-even correlations adjusted by the Spearman-Brown prophecy formula.…

Investigated Kaufman's procedures for determining intersubtest scatter on the Wechsler Intelligence Scale for Children-Revised by means of Sattler's revised tables for determining significant subtest fluctuations. Results indicated that Sattler's revised tables yielded more conservative estimates of subtest scatter than those originally reported…

Equations were derived for estimating MMPI (Minnesota Multiphasic Personality Inventory) scores from a short form developed for cognitively impaired individuals. Multiple regression analyses demonstrated that prediction from a single short-form scale was acceptable and was little improved by the addition of other scales or sex of subject to the…

Presents four tables for the statistical interpretation of factor scores on the Wechsler Intelligence Scale for Children-Revised. Provides the percentile equivalents of factor scores; the significance of differences between factor scores; the frequency with which specified discrepancies occur; the significance of differences between a factor score…

Diagnostic hit rates for the Diagnostic Inventory of Personality and Symptoms were compared to diagnosis by psychiatrists of the same patients. The Probability Scale employing Bayesian concepts and base rates correctly classified 70% of the patients and was more accurate by far than the other two methods used. (Author/ABB)

A simple unbalanced block model is proposed for examination marks, as an improvement on the usual implicit model. The new model is applied to some real data and is found, by the usual normal linear theory F test, to give a highly significant improvement. Some alternative models are also considered. (Author)

The author presents a formula for scoring true-false and multiple-choice questions which produces a score directly related to the number of incorrect alternatives the student is able to eliminate on each question.

Results of recategorizing the Wechsler Intelligence Scale for Children (Revised) subtest scores of 159 black learning disabled primary grade children into spatial, conceptual, and sequential scales as recommended by A. Bannatyne led to the conclusion that the diagnostic utility of the Bannatyne recategorization is questionable. (Author/DB)

Seventeen statistics for measuring the reliability of criterion-referenced tests were critically reviewed. The review was organized into two sections: (1) a discussion of preliminary considerations to provide a foundation for choosing the appropriate category of "reliability" (threshold loss function, squared-error loss-function, or…

It is important for counselors to understand the problems involved in testing students and also how to properly evaluate test results. This article discusses both areas. (HMV)
