The purpose of this article is to exemplify and enhance the place of modelling as a qualitative process in educational research. Modelling is widely used in quantitative research as a tool for analysis, theory building and prediction. Statistical data lend themselves to graphical representation of values, interrelationships and operational…

Several developments in the use of the new method of meta-analysis give cause for optimism. First, different meta-analysts are doing work in the same areas, leading to increased confidence in meta-analytic results. Second, meta-analysts are beginning to include raw data in their reports, which helps readers pinpoint the exact studies that lead to…

Education statistics are rarely neutral; those who collect and analyze them have different purposes. In this article, Bracey discusses several principles of data interpretation to help educators avoid falling into statistical traps. For example, because such reports as A Nation At Risk contain many "selected, spun, distorted, and even manufactured…

This document reviews "The Collected Works of George E. P. Box," edited by G. C. Tiao. The two-volume collection is divided into five parts. Each part is prefaced with an introduction by a statistical researcher giving his view of the motivation and highlights of the papers presented. The 16 papers in Part 1 on statistical inference,…

Reviews a model by Joel Kleinman (proposed in this issue) for comparing State infant mortality rates to long-term trends. Asserts that even States with non-significant test results may have problems needing attention. Argues that the model may not be practically applied by State health officials. (KH)

Points out that 108 studies in the first 25 volumes of AV Communication Review used univariate analysis of variance to test experimental hypotheses, and suggests that researchers include omega-squared values in their reports to permit estimation of the relationship between x and y variables, and correlation data for comparing studies.

Although the courts have established that there are several ways of determining adverse impact of hiring practices, the criteria the courts have used to consider cases seem to be primarily the source, scope, and sufficiency of statistics offered as evidence. (Author/IRT)

Statistics tend to become interesting to non-methodologists when taught in a research context that is relevant to them. Real data sets supplemented by sufficient background information can provide just such a context. Despite this, many textbook authors and instructors of applied statistics rely on artificial data sets to illustrate statistical…

This paper addresses conflicting views on whether there is now or will soon be a surplus of college graduates and other skilled workers by analyzing data from the Bureau of Labor Statistics (BLS). Ten questions (and the answers reached) are addressed: (1) "Do the latest BLS projections of college graduate supply actually predict a bust--a…

Focuses on problems in making machine-readable data files (MRDFs) accessible and in using them: quality of data in MRDFs themselves (social scientists' concern) and accessibility--availability of bibliographic control, quality of documentation, level of user skills (librarians' concern). Skills needed by social scientists and librarians are…

Discusses the collection by library managers of demand and use data from their own libraries on a regular basis as a means of answering management questions pertaining to the "cost" of information, staff productivity, and levels of service. Examples of statistical records and recommendations for collecting data are presented. (Author/JL)

The most advantageous relationship between computer technology and institutional research is considered. Three potential problem areas are discussed: those associated with a central data processing center, those germane to minicomputers or terminals within the institutional research office, and those nondiscriminating types which cover both…

Data collection and analysis are frequently neglected by school leaders over the course of the decision-making process. All schools gather large amounts of information about students and teachers, but most data are used to satisfy administrative requirements rather than evaluate school improvement in a systematic fashion. Apprehension regarding…

Traditional elementary statistics instruction for non-majors has focused on computation. Rarely have students had an opportunity to interact with real data sets or to use questioning to drive data analysis, common activities among professional statisticians. Inclusion of data gathering and analysis into whole class and small group activities…

The planning and management of educational systems has been examined widely in the last decades despite the lack of a standard research method and a unified underlying theory. Research based on quantitative analysis yields data that may be processed using the graphic capabilities of computers. The combination of numerical data and computer…
