Discusses the significance of confidence intervals around IQ scores based on a misleading interpretation of the standard error of measurement terms provided in the Wechsler Adult Intelligence Scale-Revised (WAIS-R) manual. Presents standard error values and a table for determining the abnormality of verbal and performance IQ discrepancies.…

Reports on study in which students of Hebrew as a second language took four versions of oral proficiency test. Results indicate that different speech styles and topics significantly affected students' scores, and correlational analyses between pairs pointed to low reliability and lack of stability of the test. Urges caution in making decisions…

This study compares differential relations between unweighted and weighted decision-making scores and selected resource variables. The findings suggest that there are few significant relationships between individual decisions and resource variables. (Author)

This discussion illustrates the application of generalizability theory to a design commonly employed in the collection of evaluation data and provides a detailed analysis of the dependability of student evaluations of college teaching. (RC)

Changes in the full scale reliability of the WISC-R were computed at three age levels when each subtest was omitted by itself. The same procedure was followed with those subtests which independently had the smallest effect in lowering full scale reliability. Cautions were noted concerning the exclusion of subtests. (Author)

Reanalysis of Wakefield and Carlson's data confirmed canonical correlations of .84 and .69, but analysis of redundancies revealed that only 34 percent of the total WISC subtest variance is redundant with the ITPA and 39 percent of the ITPA subtest variance is redundant with the WISC. (Author)

This report describes a reliability and validity study on a learning styles instrument that was developed based on the Dunn, Dunn, & Price model. That model included 104 Likert five-point scale items for investigating 24 scales grouped into five categories considered likely to affect learning. The Learning Style Preference Inventory (LSPI)…

With the rise of violent teenage crime, with an alarming number of child soldiers across the globe, and with the continually increasing number of children and adolescents who are victimized by violence and war, an instrument that measures nonviolent tendencies would be very useful. The Teenage Nonviolence Test (TNT) was recently developed and…

This research study was designed to establish the reliability of the Teenage Nonviolence Test (TNT). The consistency and factor structure of the TNT using a sample of 376 adolescents were evaluated. The stability of the TNT was assessed over time by administering the TNT twice with a two week intervening interval to 87 adolescents. The TNT appears…

There is variability in the estimation of an equating transformation because common-item parameters are obtained from responses of samples of examinees. The most commonly used standard error of equating quantifies this source of sampling error, which decreases as the sample size of examinees used to derive the transformation increases. In a…

Article commented on a study by Harris, who presented formulas for the variance of errors of estimation (of a true score from an observed score) and the variance of errors of prediction (of an observed score from an observed score on a parallel test). (Author/RK)

This paper provides data that relate to both the reliability and abnormality of differences for the Developmental Test of Visual Perception (DTVP) subtest scores. (Author)
