Latent trait model calibration procedures were used on data obtained from a group testing program. The one-parameter model of Wright and Panchapakesan and the three-parameter logistic model of Wingersky, Wood, and Lord were selected for comparison. These models and their corresponding estimation procedures were compared, using actual and simulated…

Ten modules which present specific instructions for conducting a task survey are provided in this manual for vocational educators, supervisors, and directors. Each module contains a short descriptive paragraph of the contents of each module, a performance objective, readings, exercise activities, and feedback for those activities. The modules are…

This report is part of the Florida Department of Education, Title III, ESEA, Educational Needs Assessment study and deals exclusively with information and data collected from questionnaires administered to a sample of seven educationally relevant subpopulations within the State. These subpopulations included students, teachers, principals,…

This article examines statistical issues raised when standard methods are used to analyze educable placement data to determine possible racial discrimination. An alternate approach is offered that detects disparities while avoiding the pitfalls of present methodologies. (BS)

The validity of logistic test models and computer simulation methods for generating sampling distributions of item bias statistics was evaluated under the hypothesis of no item bias. Test data from 937 ninth-grade students were used to develop 7 steps for applying computer-simulated baseline statistics in test development. (SLD)

Mental health consumer-run organizations are alternatives to mainstream mental health services, and they have the dual focus of supporting members and creating systems change. The existing literature suggests that these organizations have beneficial impacts on social support, community integration, personal empowerment, subjective quality of life,…

The nine-volume Survey Kit is designed to help readers prepare and conduct surveys and become better users of survey results. All the books in the series contain instructional objectives, exercises and answers, examples of surveys in use, illustrations of survey questions, guidelines for action, checklists of "dos and don'ts," and…

Issues pertaining to research on college reading and study skills programs are analyzed, based on a literature review. It is suggested that before educators can provide quality instruction, they need to differentiate practices that are conducive to learning. Evaluative criteria are needed to make such decisions, as well as to design and evaluate…

The measurement of change is such a broad topic that this article must limit its focus to a few specific subtopics. These specific topics include: longitudinal research design, attrition in research studies, the statistical analysis of difference scores, and the comparison of analysis of variance (ANOVA) and multivariate analysis of variance…

The report traces the activities which led to the development of the adjusted weights--beginning with the basic National Longitudinal Study design, the base-year weight calculations, and the resurvey procedures. Next, the report describes the first follow-up weight calculations (including unadjusted student weights), nonresponse adjustment…

This notebook contains 21 standards established by the Center for Educational Statistics (CES); CES legislation; and a description of the CES publication and publication review processes. The publication clearance procedures and the external advice and peer review policies are established by the Office of Educational Research and Improvement…

The Armed Services Vocational Aptitude Battery (ASVAB), a battery of 10 vocational tests, was administered to a national probability sample of nearly 12,000 young people, 15 to 23 years of age. Score distributions from the study were needed by the Armed Services to set performance levels for accepting and assigning recruits. Three psychometric…

The statistical properties of two methods of estimating gain scores for groups in quasi-experiments are compared: (1) gains in scores standardized separately for each group; and (2) analysis of covariance with estimated true pretest scores. The fan spread hypothesis is assumed for groups but not necessarily assumed for members of the groups.…

The Rasch model for test score equating was compared with three other equating procedures as methods for implementing the norm referenced method (RMC Model A) of evaluating ESEA Title I projects. The Rasch model and its theoretical limitations were described. The three other equating methods used were: linear observed score equating, linear true…

A linear regression model was used to select items from a pool of 700 arithmetic word problems to be used in a computer-assisted mathematics curriculum for elementary school students. The experimental procedure first involved a stepwise linear regression analysis of a student's performance over a set of 25 problems. The probability correct for…
