Meta-analysis was used to conduct an integrative review of the research on modifying attitudes toward persons with disabilities. Prior reviews, using small samples and lacking systematic data collection and analysis, were unable to draw firm conclusions about the effectiveness of attitude modification techniques. In the hope of correcting these…

Data and information needs of college administrators are discussed, along with the uses of information to support decisionmaking. Difficulties in applying information technology to the administration of higher education are briefly reviewed. Data and information are discussed both in definitional and functional terms. Data are defined as either…

The focus of this study was on the visual analysis of time series data for evaluating educational programs. Two characteristics of the data--changes in slope and variability--and two characteristics of evaluation--training in data utilization and the use of aimlines/decision rules--were manipulated. A total of 51 students and/or teachers in…

A Rasch measurement model can be constructed to meet the requirements of rank ordered data. If multiple rankings of the same objects are available, then the parameters of the objects can be estimated, along with their standard errors and also with statistics summarizing the fit of the data to the measurement model. This paper summarizes the…

This document provides information on the Data on Vocational Education (DOVE) plan, which has provided the National Center for Education Statistics (NCES) with a framework on which a viable data collection and dissemination program is being constructed for vocational education. A section on the status of DOVE discusses the attainment of the…

A study was conducted to investigate the reading comprehension and educationally related characteristics and relationships that describe the Navy's recruit population. The variable of primary interest was the recruit's reading comprehension grade level score; other variables were years of education, aptitude score, high school graduation status,…

Various methods have been suggested for the analysis of data collected in research settings where random assignment of subjects to groups has not occurred. For the purposes of this paper the set of allowable nonrandomized designs is made up of those research designs where data are collected for one or more groups of subjects at two or more time…

Designed to assist persons who need to compare and use information obtained under various classification systems, this volume links the Department of Education vocational program categories in the new Classification of Instructional Programs (CIP) to the occupations in the Dictionary of Occupational Titles (DOT), the Standard Occupational…

The report addresses the question of the structure of cognitive abilities, i.e., how many different abilities should be identified and the relations between abilities. Models suggested by Spearman, Thurstone, Guilford, Vernon, Cattell-Horn and others are reviewed. By combining features of the Vernon and Cattell-Horn models it is possible to…

There has recently been a tremendous increase in the quantity of research published in gerontology. While the increase in the quantity of research has been regarded positively by gerontologists, there has been little discussion or evaluation of the quality of the research. Two articles that appeared in 1975 were both very critical of…

An introduction to the conventions of research design and statistical analysis is presented for graduate students of applied linguistics. The chapters cover such concepts as the definition of research, variables, research designs, research report formats, sorting and displaying data, probability and hypothesis testing, comparing means,…

This paper presents the elementary mathematics behind the traditional cost-volume-profit model of the business firm in both deterministic and probabilistic forms. By a simulation process the structure could be modeled to derive a wide variety of data analysis sets for use in the classroom. The data sets can be used to aid students in applying…
