This chartbook is designed as a graphic reference on national statistical information about disabilities. Each page contains a content question, explanatory text, and an explanatory chart or table as well as information on sources used. Key terms are shown in boldface and defined in a glossary. Section 1 provides demographic data on Americans with…

The objective of the study is to convince educational researchers of the necessity for "standard mastery curves" for the graphical representation of scores on summative tests for a group of students. Attention is drawn to the study of theoretical and empirical skew curves in education and biology. Use of standard mastery curves and study…

The purpose of this study was to determine trends and difficulties concerning student incident reports within the residence halls as they relate to the incident reporting system from the Department of Housing and Residential Life at a Southeastern Doctoral I Granting Institution. This study used the frequency distributions of each classified…

Canonical analysis of two convex polyhedral cones involves looking for two vectors whose square cosine is a maximum. New results about the properties of the optimal solution to this problem are presented. The convergence of an alternating least squares algorithm and properties of limits of calculated sequences are discussed. (SLD)

Inference, or decision making, is seen in curriculum documents as the final step in a statistical investigation. For a formal statistical enquiry this may be associated with sophisticated tests involving probability distributions. For young students without the mathematical background to perform such tests, it is still possible to draw informal…

This study was conducted to analyze and summarize raw data obtained from a 1972 study: "Report on a Cost Study of Specific Technical Processing Activities of the California State University and College Libraries" with the hypothesis that the cost of technical processes increases as the production volume both rises above and falls below…

The purpose of this research is to evaluate the effectiveness of the area (homogeneous) scales of the Navy Vocational Interest Inventory (NVII) as predictors of Class "A" school achievement and as measures of rating differentiation by comparing specific occupational scales with more general interest measures--the NVII area scales. The…

Examines two traditional approaches to the measurement of library service--the gathering of circulation and reference statistics--and relates them in a statistical model in an attempt to define real standards against which a library's activity can be compared. Graphs comparing reference and circulation statistics are included. (Author/JD)

This reexamination of earlier forecasts and statistics related to research library growth--Purdue studies first published in 1965, data and forecasts from Fremont Rider's 1944 book--shows mixed results for evidence of continuing rapid growth of collections and acquisition expenditures and marked decline in acquisition rates.

Although single-subject research techniques are valuable to counselors, analyzing change by graphs alone is open to major sources of error. Discusses these sources and explores the issues of serial dependency, unreliability of graphs, interjudge disagreement on graphed data, and the use of time-series statistics with relevance to the counselor in…

Introduces Q-analysis, a methodology for investigating a wide range of structural phenomena that defines structures in terms of relations between members of sets and reveals their salient features by using techniques of algebraic topology. Applications relevant to librarianship and information science are reviewed and present limitations…

This instructor guide, which was developed for use in a manufacturing firm's advanced technical preparation program, contains the materials required to present a learning module that is designed to prepare trainees for the program's statistical process control module by improving their basic math skills in working with line graphs and teaching…

In a series of three independent studies that focused on the classic sources of curriculum (the learner, society, and subject matter), data were gathered that might bear on the choices facing the curriculum developer. Learner data tentatively revealed what characteristics of pictures affected the deployment of third-grade children's visual…

Discusses the relative ease of obtaining library management statistics when using machine readable records and powerful software tools such as the Statistical Analysis System package. The development of such a management information system for the Cataloging in Publication division of the Library of Congress is described. (Seven notes with…
