This article looks at the problem of obtaining accurate income data from cross-sectional surveys and explores the implications of rounding of income to the class boundaries when using grouped data. (Author/RM)

The reluctance to use film and video equipment for systematic observation and recording can be partially attributed to an assumption of reactivity and internal invalidity. The results of the study discuss placement of the observer and the use of film in data collection. (Author/DEP)

Libraries need solid information upon which to base collection development decisions. Specific evaluative methods for determining scope, access, and usefullness are described. Approaches used for data collection include analysis of interlibrary loan requests, comparison with major bibliographies, and analysis of accessibility through available…

Jensen's arguments that the anomalies in Sir Cyril Burt's kinship data are due to carelessness are critically examined. (Author)

The portfolio approach to self-evaluation is possible with limited staff time or funds. Evaluators collect a variety of documents and records that describe the goals, perceptions and values involved in the program. The portfolio items should represent key issues and precipitate useful discussions. (GDC)

The Needs Assessment Process consists of four phases; design, data gathering, analysis and summarization, and action-taking. A brief description of some of the key humanistic competencies needed in each phase were presented. (Author/RK)

A preliminary investigation of parameter estimation for planned incomplete data in educational research used an algorithm to estimate correlations for each of two sets of six variables, based on correlational data obtained from previous studies. The algorithm gave the estimator that is maximum likelihood for data with a multivariate normal…

A monetary gratuity's effect on the return rate (RR) of a mail survey was studied. Half of the surveys mailed to 507 librarians in Arizona included a 1.00 dollar gratuity. The RR was 80% among those receiving the gratuity and 59% among controls. A survey's RR and consequent validity may be improved by including a gratuity. (SLD)

Describes the new design for the National Assessment of Educational Progress. Changes include a biennial schedule, expanded sampling, and balanced--incomplete spiralling of exercises and variables to permit the estimation of intercorrelations. Changes should improve the interpretability, comparability, timeliness, and policy relevance of the data.…

The accuracy of teaching and determination of student progress with and without data collection were measured for three teaching assistants in classrooms for severely handicapped adolescents. Results appeared to support theories that teachers' subjective judgments of student performance are more prone to error than those based on recorded data.…

This publication presents estimates of drug-related emergency department (ED) episodes from the Drug Abuse Warning Network (DAWN) from 1994 through the first half of 2001. DAWN is an ongoing, national data system that collects information on drug-related visits to EDs from a national probability sample of hospitals. This publication marks a major…

This paper takes as its data the assumptions, processes of deduction, and data types used in leading publications of historiometric studies of creativity. The paper uses this data to question the philosophical assumptions of the historiometrics of creativity from within its own positivist paradigm and to argue that its conclusions are…

Creating a survey that asks the right questions at a level appropriate for the intended audience is a difficult task. This guide is designed to support educators who want to be confident that the data they gather will be useful. The guide is organized according to the developmental steps in creating a survey. Individual chapters correspond to the…

An evaluation of a technique for minimizing subject-observer interaction is presented. The data show that nine children with school-adjustment problems looked less frequently at observers wearing sunglasses than at observers without sunglasses. (Authors)

The author concludes that the ideographic nomothetic technique adapted to the classroom can teach the model implicit in the technique while at the same time creating a set with which to examine personality. (Author)
