A subset of Statistical Process Control (SPC) methodology known as Control Charting is introduced. SPC methodology is a collection of graphical and inferential statistics techniques used to study the progress of phenomena over time. The types of control charts covered are the null X (mean), R (Range), X (individual observations), MR (moving…

This document describes the review, analysis, and decision-making process that Trinity University, Texas, went through to develop the three-part computer network that they use to gather and analyze EEG (electroencephalography) and EKG (electrocardiogram) data. The data are gathered in the laboratory on a PDP-1124, an analog minicomputer. Once…

The potential uses of microcomputers in evaluation research are discussed in this pamphlet. At the beginning, a matrix is provided showing the relationship between the steps in the evaluation research process and common types of computer software. Thereafter, the guide is organized sequentially around the evaluation research activities that are…

A systematic analysis of dissertation research on stress in educational administration, using a sample of 44 dissertations completed from 1969 to 1982, inventoried these studies' topics, evaluated their conception, design, and methodology, and synthesized their findings. It was found that the bulk of the dissertation literature has focused on the…

This document investigates the widely used school climate assessment instrument, the CFK Ltd. School Climate Profile. Part A (General School Climate Factors) was administered by school to a junior high campus (n=257) and a high school campus (n=906) in a major metropolitan area in the Southwestern United States to gather data for administrative…

A normally distributed data set of 1,000 values--ranging from 50 to 150, with a mean of 50 and a standard deviation of 20--was created in order to evaluate the bootstrap method of repeated random sampling. Nine bootstrap samples of N=10 and nine more bootstrap samples of N=25 were randomly selected. One thousand random samples were selected from…

Differential item performance (DIP) is discussed as a concept that does not necessarily imply item bias or unfairness to subgroups of examinees. With curriculum-based achievement tests, DIP is presented as a valid reflection of group differences in requisite skills and instruction. Using data from a national testing of the ACT Assessment, this…

Taking into account an imperfectly operating labor market, this paper measures and contrasts average and marginal returns on secondary education in two adjacent East African countries (Kenya and Tanzania) with very similar economic structures. The marginal rate of return seemed somewhat lower than the average rate of return. Includes three tables…

Statistical measures of practical significance report the extent to which variation in the dependent variable can be explained by the independent variable. Reports of special education research sometimes discuss practicality using the estimate of statistical significance. Practical significance, however, may vary greatly among samples even though…

This bibliometric investigation of literature on microcomputers in library and information services focuses on the years 1973-1986. Five printed reference tools and three online databases were searched to examine the number of publications, types of documents, contributing languages and countries, and the productivity of individual authors.…

This study of training needs utilized a questionnaire to assess participant's opinions of knowledge level that should exist and knowledge level that does exist in 25 content areas and analyzed the resultant data using three different approaches: mean difference analysis, multicomponent data analysis, and weighted need index.

"Empirically Based Play Interventions for Children" is a compilation of innovative, well-designed play interventions, presented for the first time in one text. Play therapy is the oldest and most popular form of child therapy in clinical practice and is widely considered by practitioners to be uniquely responsive to children's developmental needs.…

Contrasted are engineering statistics with statistics for students of mathematics and social science. Topics considered are level of abstraction, amount of technical detail, and choice of subject. The nature of exercises suitable for various courses is described. (KR)

Examining National Center for Health statistics, questions whether fictional television accounts of teenage suicide affect the teenage suicide rate. Assesses four films about teenage suicide, nationally televised in 1984 and 1985. Accounts for holiday and temporal effects, television new stories, and large city influences. Finds that the films did…

Counters the popular misconception that poverty is linked to adolescent values that result in pregnancy and irresponsibility. Suggests the following research agenda: (1) reinterpretation of census data; (2) a focus on individual decision-making and systemic forces; (3) dissemination of data; and (4) investigation of father's role.
