We extend a unified and easy-to-use approach to measurement error and missing data. In our companion article, Blackwell, Honaker, and King give an intuitive overview of the new technique, along with practical suggestions and empirical applications. Here, we offer more precise technical details, more sophisticated measurement error model…

This paper examines some of the problems that arise when conducting multivariate analyses with incomplete data. The literature on the effectiveness of several missing data procedures (MDP) is summarized. The most widely used MDPs are: (1) listwise deletion; (2) pairwise deletion; (3) variable mean; (4) correlational methods. No MDP should be used…

This report investigates the appropriateness of using the General Technical (GT) composite of the Armed Services Vocational Aptitude Battery (ASVAB) as a reenlistment criterion. Three aptitude measures, all ASVAB composites, were compared to measures of proficiency in job performance: the Armed Forces Qualification Test (AFQT), the GT, and the…

This paper discusses the principles underlying discriminant analysis and constructs a simulated data set to illustrate its methods. Discriminant analysis is a multivariate technique for identifying the best combination of variables to maximally discriminate between groups. Discriminant functions are established on existing groups and used to…

One of the important underlying assumptions of all item response theory (IRT) models is that of local independence. This assumption requires that the response to an item on a test not be influenced by the response to any other items. This assumption is often taken for granted, with little or no scrutiny of the response process required to answer…

A concurrent validity study of the Computer Attitude Scale (CAS) was undertaken to index criteria-related validity through available performance evaluation data of 47 computer programmers and operators at a large, Midwest public utility organization. A Pearson product-moment correlation coefficient of CAS scores with performance evaluations…

The goal of this research was to predict from a recruit's responses to the Armed Services Vocational Aptitude Battery (ASVAB) items whether the recruit would pass the Armed Forces Qualification Test (AFQT). The data consisted of the responses (correct/incorrect) of 1,020 Navy recruits to 200 items of the ASVAB together with the scores of these…

A public school district in Alabama uses the Otis Lennon School Ability Test (OLSAT) in place of the Wechsler Intelligence Scale for Children (Revised) (WISC-R) as a screening device for students who are referred for possible special education placement. To determine the relationship between the two tests, Pearson product moment correlation…

Measures of survival skills, locus of control, study skills, achievement test scores, and grade point average for 86 students (ages 11-15) with behavioral disorders were analyzed to identify the correlates and predictors of their academic achievement. Overall, student achievement test performance was correlated with organizational skills and an…

Data from the areas of job satisfaction and job stress are used to illustrate the following points: (1) that measurements can be arranged conceptually along a continuum from the specific to the global (or general); (2) that scales can be constructed which represent different levels of generality, within the same content area; (3) that such scales…

An extensive body of research indicates that men on the average achieve higher scores in mathematics than women. Despite this extensive research, conclusions about sex differences in mathematics achievement have suffered from various inadequacies in the use of measures of association among coursework experiences, sex, and other correlates of…

This study of U.S. college students' soap opera viewing habits investigated their motives; interrelationships among motives, audience viewing dispositions, and life patterns; whether viewing dispositions and life pattern variables explain viewing motives; and what multivariate structures explain relationships between viewing motives, viewing…

This study was an examination of the usefulness of a statistical regression approach to identify prospective Engineering and Information and Computer Science (ICS) applicants most likely to succeed at the University of California at Irvine (UCI). The specific purpose was to determine the extent to which preadmissions measures such as high school…

This study examined the need to develop reliable and valid procedures for screening large populations for possible speech and language problems and the use of the Fluharty Preschool Speech and Language Screening Test (FPSLST) as such a device. The test was administered to 260 preschool children, ages three to six. There were 166 Blacks and 94…

School effectiveness indices (SEIs) based on residuals from regressing test performance in reading and mathematics onto prior-year test performance and a socioeconomic status measure (percentage eligible for a subsidized lunch program) were obtained for two consecutive years for 431 South Carolina elementary schools. The analysis involved school…
