Proposes and illustrates a new method by which "what if" analyses can be conducted using estimated true population effects. Use of these "what if" methods may prevent authors with large sample sizes from overinterpreting their small effects once they see that the small effects would no longer have been statistically significant with only a…

Using item response theory, discusses the difficulties faced in evaluating measurement invariance when a psychological construct is assessed through a test or inventory composed of categorical items. Illustrates the usefulness of fitplots in assessing measurement invariance in inventory data. (SLD)

In this article, the author reviews the Reynolds Intellectual Assessment Scales (RIAS), an individually administered test of intelligence appropriate for ages 3 through 94 years with a conormed, supplemental measure of memory. The RIAS should be administered by examiners who have formal training in assessment. In this regard, the RIAS is a…

Factorial analyses differ from nonfactorial analyses in that in the former all possible hypotheses (all possible main effects and interaction effects) are tested regardless of their substantive interest to the researcher and their interpretability, while in the latter, only substantive and interpretable hypotheses are tested. This paper shows the…

Rotation is used in almost all exploratory factor analysis (EFA) studies. There are numerous rotation strategies that can be employed in these various applications. This paper reviews the various rotation choices in EFA studies, including confirmatory rotation, and presents criteria useful in selecting rotation methods in various analytic…

This keynote address begins with examples that underscore how profoundly the issues of multiculturalism and diversity impact the consciousness of society at the end of the 20th century.

The booklet describes seven assessment instruments that may be helpful in planning educational programs for mildly educationally handicapped secondary students. Each instrument is outlined in terms of ordering information, target population, areas assessed, materials included, time required for administration, group size, format and…

In the use of projective tests, there is a certain role of responsibility that should be maintained in the administration of these tests and their interpretations. Thoughts regarding these factors are expressed in this article. (DEP)

Three hypotheses were tested. (1) The test results come from a scalable universe. (2) The data from the two sections come from the same scalable universe. (3) A confirmation of the second hypothesis does not insure that the actual performance levels come from the same universe. (Author)

The intention of the study was to show that reliance on performance on New York Survey (mathematics) and National Educational Development Tests for the purpose of identifying individuals for guidance in mathematics might exclude creatively gifted children. (Author)

Climate surveys are an important diagnostic tool in organization development. The purposes of this paper are to: (1) present the advantages and disadvantages of using a survey as a diagnostic tool, as compared to interviewing, observation, and the use of secondary (preexisting and non-intrusive) information; (2) argue for customized climate…

Article focuses attention on some of the more important factors to be considered in evaluating educational products and programs within the domain-referenced framework. (Author)

An investigation which compared five ways of expressing information about the choice of questions to be made from different sections of a test paper. (Author)

In this study only bias in scoring, controlling for the effect of actual administration, was investigated. Results indicated that scoring the WISC was biased by scorers' expectations, and that the bias effect exists independent of actual administration of the test. (Author)
