Defines the concept of relative effectiveness, describes the construction of an instrument to identify relatively effective children, reports experiments to validate the concept and method of measurement, and discusses the relevance of these to issues in educational procedures, predictions of situational behavior, and other concepts that have been…

Correlations between the two screening tests and between the screening and criterion measures were inconsistent with prediction rates based on classificational screening test scores. On the basis of correlational validity coefficients, relationships between measures in this study would have been overestimated. (Author/SBH)

The test-retest reliability and predictive validity of developmental quotients (DQs) derived from the Cattell Infant Intelligence Scale was assessed with 83 children with mental retardation, age 30 months or more. Scores were impressively stable on retest. DQs derived from the Bayley Scales of Infant Development were superior to Cattell DQs in…

The study, comparing 27 pairs of mildly mentally retarded students and normal achievers (ages 6-8), found that mentally retarded subjects evidenced lower performance on experimental oddity problems but were able to generalize to very different oddity arrays. High levels of sensitivity, specificity, positive predictive accuracy, and negative…

Statistical analyses of scores on subtests of the Intelligence Test for Visually Impaired Children were done for two groups of children, either with or without usable vision. Results suggest that the battery has differential factorial and predictive validity. (Author/DB)

Among the various tests employed in personnel selection, handwriting analysis, or graphology, has enjoyed long-standing international popularity despite being highly contentious. This report contains not only an evaluation of the current published scientific reviews on the use of graphology in personnel selection, but also an evaluation of several…

The present study was conducted to determine whether combining the results of multiple actuarial risk scales increases accuracy in predicting sex offender recidivism. Multiple methods of combining 4 validated actuarial risk scales--the Violence Risk Appraisal Guide, the Sex Offender Risk Appraisal Guide, the Rapid Risk Assessment for Sexual…

This article presents the results of a factor analysis on the distance education surveys "Is Online Learning Right for Me?" and "What Technical Skills Do I Need?" Both surveys are 15-question, forced response, self-scoring guides that have face validity for individual traits and skills believed to contribute to potential success in an…

A United States Employment Service (USES) General Aptitude Test Battery (GATB) plan was formulated to evaluate and develop additional job-related assessment methods. Eighteen alternative predictors were reviewed, from which biodata was selected for development. The literature indicates that biodata provides increased validity with little or no…

The manual for the McCarthy Scales of Children's Abilities (MSCA) cites a study of concurrent validity. A partial replication of the study yielded lower means and larger standard deviations for five of the MSCA scales and for the Stanford-Binet. (Author)

Intended to determine the validity of the total score on the Graduate Record Examinations Aptitude Test (GRE) and of the score on the Miller Analogies Test (MAT) as predictors of a criterion of completion or noncompletion of the Doctoral Program in Educational Administration at State University of New York at Albany.

Paper presented at the International Seminar on Experimental Research in Music Education (University of Reading, Reading, England, July 9-16, 1968).

The Metropolitan Readiness tests, first published in 1948 (forms R and S), were revised in 1966 (forms A and B). This study was instigated as a result of the charge that the revisions of the tests made them more difficult and more unfair to deprived children. Thirty-six Caucasian beginning first graders (divided evenly by high and low…

Validities of the four aptitude indexes of the Armed Services Vocational Aptitude Battery (ASVAB), Form 1, and the Airman Qualifying Examination-66 (AQE), were determined for final grades in 46 airman training courses. Comparisons were made between AQE and ASVAB in terms of their ability to predict technical school success. The data demonstrate…

Expectancy tables are discussed as a device for interpreting the meaning of test results for those untrained in statistics. Three ways of organizing an expectancy table are discussed: (1) to determine the probability that a student with a given test score will succeed in a specified course; (2) to find out how to pick the best applicants; and (3)…
