Decomposable models, which allow for the interdependence of structure among observable variables, are described. Each model is fully characterized by a set of conditional interdependence restrictions and can be visualized with an undirected as well as a special type of directed graph. (Author/JKS)

Samples in research on individual and group differences may be selected based on whole scores which differ from the population mean. Children are diagnosed in clinical practice with a whole score. These procedures produce regression to the population mean which can affect accuracy and adequacy of part score interpretations. (Author/DWH)

The purpose of this study was to determine the concurrent validity of the Learning Ability Profile (LAP) by correlating the results obtained on the LAP with grade point average (GPA). Scores on LAP, both weighted and nonweighted, were correlated .30 and .31, respectively, with GPA. (Author/BW)

The Locus of Control Inventory for the Deaf (LCID), consisting of a 23-item Likert-like scale, and two commonly used scales to assess locus of control in hearing persons were administered to 174 deaf freshman students. Intercorrelation findings demonstrated greater soundness of the LCID as compared with the other scales. (Author)

Reanalysis of a study re: the impact of bussing on student achievement constitutes the basis for a four-article debate on the statistical validity of the original study and that of its critic. (JC)

Positive intercorrelations between physical and occupational therapy test items were demonstrated in testing of learning-disabled children with perceptual deficits. (GW)

Missouri Children's Picture Series (MCPS) Aggression scale scores and four more traditional measures of aggression were intercorrelated for 40 normal fourth-grade boys. (Editor)

A more generalized error model for time-limit tests is developed. Model estimates are derived for right-attempted and wrong-attempted correlations both within the same test and between different tests. A comparison is made between observed correlations and their model counterparts and a fair agreement is found between observed and expected…

The gaps in school achievement among racial and ethnic groups and between students from poor and nonpoor families are well documented. They are large, and have been persistent. This publication is about conditions that help create and perpetuate achievement gaps. It focuses on the many antecedents of differences in school achievement college-going…

This paper reports an exploratory study that is the second in a series concerned with measuring Internet visibility as it influences colleges and universities. The purpose was to examine one possible source of Internet visibility, the association of eminent alumni with particular colleges and universities. College-educated U.S. presidents were…

Extensive research has explored job satisfaction, job performance, and the financial performance of organizations. Job satisfaction and job performance have been explored separately and collectively. However, scholars only have begun to explore the relationship between employee job satisfaction and financial performance of organization. This paper…

Often during budget time, school boards are faced with the dilemma of whether to designate funds for teachers and teaching materials or for buses and buildings. Frequently, this leads to the impression that buses and buildings consume too much of the budget and have no direct relationship to the student. This report examines the validity of this…
