Factors affecting a lower-bound estimate of internal consistency reliability, Cronbach's coefficient alpha, are explored. Theoretically, coefficient alpha is an estimate of the correlation between two tests drawn at random from a pool of items like the items in the test under consideration. As a practical matter, coefficient alpha can be an index…

The validity of the Personality Diagnostic Questionnaire-Revised (PDQ-R) was examined. The PDQ-R and the Crowne-Marlowe Social Desirability Scale (SD) were administered in the spring of 1989 to 45 undergraduates (26 females and 19 males) at Gettysburg College in Pennsylvania. One month later, the Hopkins Symptom Check List (SCL-90) was…

This study investigates the validity of the Stanford Binet Intelligence Scale-Fourth Edition (S-B:4) for use with students with learning disabilities. It compares the performance of 18 elementary-age students on the S-B:4 and the Kaufman Assessment Battery for Children (K-ABC). The subjects were identified by their school as having learning…

This paper discusses cognitive and noncognitive variables, and their relationship with each other, in learning and in educational evaluation. The nature of noncognitive learning environment variables is examined. The following instruments that have been widely used in assessing classroom environment are described: (1) the Learning Environment…

The term "ipsative" refers to measurement based on intra-individual comparisons. The research literature in the social sciences contains many cautions about using ipsative data in multivariate analysis. The purpose of this paper is to identify the problems associated with the multivariate and regression analyses of ipsative data and to…

An interactive, self-guided program for the joint post-processing of bibliographic citations from the federal information centers of the Department of Energy (DOE), the Department of Defense (DOD), and the National Aeronautics and Space Administration (NASA) is described. The program, presently installed on the Intelligent Gateway Processor of the…

This paper reviews recent work in factor analysis of categorical variables. Emphasis is on the generalized least squares solution. A section on maximum likelihood solution focuses on extensions of the classical model, especially the normal case. Many of the recent developments have taken place within this context, and it provides a unified…

A geographically-based, random sample of 62 children, balanced for child gender, and their mothers who met selection criteria were observed and interviewed to determine the correlates of rural children's mental development. It was hypothesized that rural children's intellectual development would be positively correlated with a number of ecological…

This study analyzed the enrollment of two computer classes at a public high school in northern Indiana to see if there was any computer inequity. The two classes examined--an introduction to computers course and a computer programming course--were studied over a period of four years. The sample consisted of 388 students in four years of the…

Prior to 1979, DeKalb Community College (DCC) developed placement levels from Scholastic Aptitude Test (SAT) scores as criteria for admissions to degree-granting programs. When this procedure proved inadequate for degree admissions and student placement, DCC began generating placement levels on the basis of the Reading, English, and Mathematics…

Meta-analytic techniques were used to analyze the effects of age, education, and work experience on General Aptitude Test Battery (GATB) validities and test scores. The sample consisted of 30,568 subjects from 143 Specific Aptitude Test Battery (SATB) validation or revalidation studies analyzed since 1972. The effect of these three variables on…

A comparison of responses, gathered in 1970 and 1987, to the "Composition Opinionnaire" which was prepared by the Commission on Composition of the National Council of Teachers of English to meet the critical needs of schools in 1970, was designed to determine any change or lack of change in teachers' values concerning the described…

The purpose of this study was to examine the variable of estimated earnings in order to determine how forecasts might be utilized to develop a securities portfolio strategy. The hypothesis stated that there is an inverse relationship between projected change in earnings per share and security performance. Ninety-one New York Stock Exchange…

The overlap of the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Halstead-Reitan Neuropsychological Battery (HRNB) was investigated in light of their use in diagnosing children's learning problems. Scores for 1,181 children in the WISC-R and the HRNB were related using a canonical correlational analysis. One significant…

The purpose of this study was to determine if a significant relationship existed between nursing students' scores on the Mosby Assess Test and the students' scores on the National Council Licensure Examination. The subjects consisted of 172 nursing students in their last semester of the Associate Degree Nursing program at the Eastern Kentucky…
