The outcome evaluation of a Drug-Free Schools and Community Program using a case-study design and pattern-matching logic in elementary schools and high schools is described, including the use of a panel survey and qualitative interviews. The elementary school case matched predicted outcome, but the high school case did not. (SLD)

This paper describes a methodology used in an on-going retention study at New York University (NYU) to identify a series of easily measured factors affecting student departure decisions. Three logistic regression models for predicting student retention were developed, each containing data available at three distinct times during the first…

The Panel on Guidelines for Statistical Software was organized in 1990 to document, assess, and prioritize problem areas regarding quality and reliability of statistical software; present prototype guidelines in high priority areas; and make recommendations for further research and discussion. This document provides the following papers presented…

The paper reviews research on the early identification of delinquent-prone children and considers the role of prediction in developing effective delinqency prevention programs. Among issues addressed are definitions of delinquency, theories on causation, and the role of prediction in criminology. Pros and cons of prediction are examined. Among…

Stochastic difference equations of the Box-Jenkins form provide an adequate family of models on which to base the stochastic theory of human growth processes, but conventional time series identification methods do not apply to available data sets. A method to identify structure and parameters of stochastic difference equation models of human…

This paper presents a model of how the supply of applicants for public employment programs may be determined, with the information necessary to incorporate the model factors into simulation of such programs. The methodology used to estimate the size and composition of the supply population for public employment programs--how many persons would…

Statistical procedures are presented for determining ordinal and disordinal aptitude-treatment interactions with linear and curvilinear data. The paper presents a method for testing the homogeneity of group regressions for a single aptitude and provides models for expanding this test to linear and curvilinear regression planes. Procedures are…

This paper describes several situations in which generalization of statistical results is not possible by representative sampling but which is attempted using corrections for selection of groups. The situations include hiring, admissions, differential classification, guidance, test score equating, and test score scaling. Evidence of inaccuracies…

This article reviews the literature on early admission to college and describes two high-schools-within-college institutions. It critiques a paper by Dewey G. Cornell and others (EC 601 042) on predictive measurement of socioemotional adjustment of accelerated adolescent females. The article also questions the value of social adjustment for…

To determine whether the Posner task, which measures the speed at which information is retrieved from the long term memory, improves prediction of reading comprehension, 121 students from reading and study skills and teacher education courses were administered the Posner task and listening comprehension, reading comprehension, and SAT verbal…

A two-stage procedure for the analysis of pretest-posttest data was developed and illustrated. Data were reanalyzed from a quasi-experimental evaluation that assessed the effects of an intervention program to teach elementary school children aged 10 to 12 years to watch violence on television more carefully/critically. The treatment group…

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 discussion of research methodologies and performance prediction in business simulations describes a study of undergraduates that considered time in the prediction of simulation performance, and explored how relationships between performance and its antecedents vary over the simulation's duration. Hypotheses tested are explained and results of…

Learning and retention may be influenced by subtle instructional stimulus characteristics and certain visual memory aptitudes. Ten stimulus characteristics were chosen for study; 50 sequences of programed instructional material were specially written to conform to sampled values of each stimulus characteristic. Seventy-three freshman subjects…

The major purpose of this study is to further the development of procedures which minimize current limitations of creativity instruments, thus yielding a reliable and functional means for assessing creativity. Computerized content analysis and multiple regression are employed to simulate the creativity ratings of trained judges. The computerized…
