Twenty-nine steps necessary for data file preparation for secondary analysis are discussed. Data base characteristics and planned use vary the complexity of the preparation. Required techniques (file verification, sample verification, file merger, data aggregation, file modification, and variable controls) and seven associated pitfalls are defined…

The two problems examined were the effect of observers in the typical classroom and the possibility of regional bias in local observers' data. (LN)

The critical issues, in a dispute between Romney's interpretation of his results and Gillmore's interpretation, are described as whether the teacher factor should be treated as fixed or random in the analysis of variance model and what conclusions can be drawn from the results of the study.

Sibling data may be used as a covariant statistically controlling family background for testing the adequacy of age-standardized scores; for testing the interval scale of mental measurements; for analyzing correlations into between- and within-family components; and for detecting cultural sources of variance.

Evaluates "College & Research Libraries" and "Journal of Academic Librarianship" on the basis of types of articles published, structure of articles, types of statistics used, and data-collection methods. Results indicate that surveys are the primary form of data collection and descriptive statistics are used more frequently…

Included herein is the conference proceedings of the 27th Annual Conference on the Teaching of Psychology: Ideas and Innovations, sponsored by the Psychology Department of the State University of New York at Farmingdale. The conference theme for 2013 was: The Science of Learning. The Conference featured a keynote address by Victor Benassi, Ph.D.…

Changes initiated by the United States Bureau of the Census to data collection on family relationships in the decennial census of the population, the Current Population Survey, and the Survey of Income and Program Participation are reviewed. In the last 5 years, innovations have centered on developing new approaches to identifying the array of…

Possible bias due to sampling problems or low response rates has been a troubling "nuisance" variable in empirical research since seminal and classical studies were done on these problems at the beginning of this century. Recent research suggests that: (1) earlier views of the alleged bias problem were misleading; (2) under a variety of fairly…

This paper acknowledges that research on school dropouts presents problems in the definitions and computation of dropout indices. It considers a variety of methods for computing dropout rates, using dropout rates which are real and which were available at the end of the 1986-1987 school year. Fall enrollment, average daily membership, and total…

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…

A cost analysis of the problem of growing library collections shows that it is more desirable, economically and academically, to establish regional compact shelving facilities for infrequently used library materials than to discard the materials. This report develops and applies a cost model--based on the Palmour Cost Model--which examines the…

One solution to the problem of obtaining test scores in order to assess multiple outcomes of educational programs is a basically simple technique called matrix sampling. Matrix sampling is the estimation of total test score statistics by administering random subsets of test items to randomly selected students. This chapter lays out the specific…

Discriminant analysis is reviewed in terms of: (1) formulations, (2) interpretations, (3) uses, (4) issues and problems in applications, (5) recent developments and conceptualizations, and (6) general references and computer programs. Four aspects of a discriminant analysis are considered. They are: (1) separation: determining intergroup…

This document attempts to state in simple terms what is necessary as a minimum to ensure the adequate provision of educational statistics in developing countries. It has been developed for the use of Ministries of Education and other interested departments in developing countries to help them develop the basic set of statistics necessary for…

Campuses should act on salary equity issues before litigation arises. Campuses must resolve database problems, unfocused studies, problems in data interpretations, and constraints on implementing findings if they are to take timely actions. Internally motivated monitoring and court-ordered monitoring are discussed. (Author/MLW)
