The 30 papers in the area of educational statistics that were presented at the 1972 AERA Conference are reviewed. The papers are categorized into five broad areas of interest: (1) theory of univariate analysis, (2) nonparametric methods, (3) regression-prediction theory, (4) multivariable methods, and (5) factor analysis. A list of the papers…

In multivariate analysis of variance the canonical variates of one effect may be correlated with the canonical variates of another effect. When the two effects are an interaction and a main effect this correlation interferes with the interpretation of the main effect. When the two effects are both main effects the interpretation of the common…

Educational, cultural, and scientific activities of the Council of Europe are reported in this bulletin. Part I reviews the areas of higher education and research, general and technical education, out-of-school education and cultural development, and educational research and documentation together with a resume of the 22nd session of the Council…

An international conference was held to allow experts from Japan, Europe, and the United States to share their views and experiences concerning the role that computers should play in higher education. The recommendations of the conference members are summarized here. First an introductory section provides an overview of educational technology,…

The Documentation Coordination and Research Incentive Unit (UCODI) is part of an international effort to increase cooperation and coordination in investigations of the possibilities of computer-assisted instruction by providing documentation, information, coordination of research incentives, advice, and assistance to researchers, teachers, and…

Established to advise and assist in the implementation of the Environmental Education Act of 1970 (P.L. 91-516), the Advisory Council on Environmental Education has summarized its activities for the past year, 1972, in this annual report. First reviewed are some of the problems envountered by the Council, indicating it is severely handicapped by…

In a post mortem study, it is demonstrated that linear prediction is as effective as computing a negative hyper-geometric distribution for estimating test norms following matrix sampling from a total test with a highly skewed score distribution, provided the same prediction coefficient is used for all examinee groups. It is also demonstrated…

Since the development of causal path analysis by Wright, both the standardized and unstandardized procedures in path coefficient estimates have been advocated in the related literature, but the superiority of one technique over the other has not been demonstrated empirically or mathematically. In this study, the sampling properties of both…

Research on the effectiveness of graphical displays for information acquisition and retention lacks a system for classifying graph information and generating test items to assess learning. The purpose of this study was to validate a system based on two types of information and three types of informational units. Results of an analysis of variance…

The sign test is perhaps the simplest nonparametric procedure comparable to the commonly used parametric t-test. This test is easily applied which makes it useful preliminary analysis and for the analysis of data of passing interest. A large variety of its applications to education research, usually not found in the standard textbooks, is included…

When Torgerson's multidimensional scaling model is used in conjunction with the method of tetrads, derived coordinates are based on data which is assumed to be distributed normally. The object of this study was to determine the amount of error contained in derived coordinates when the normality assumption is violated. Torgerson coordinates were…

Student and alumni ratings for 23 teachers were found to correlate .75 (somewhat less for teachers rated only by graduates of their department). This substantial agreement between current students and alumni (of five years) regarding who have been effective or ineffective teachers suggest that student ratings are fairly permanent and do, at least…

Gradient methods are employed in orthogonal oblique analytic rotation. Constraints are imposed on the elements of the transformation matrix by means of reparameterisations. (Author)

The objective of the Marine Corps Training Management System (TRAMS) is to assist Headquarters Marine Corps staff agencies in the planning and management functions related to the Marine Corps 'training line'. (Author)

This study was designed to identify the major organizational and functional dimensions of large city public school research bureaus. Several (14) organizational variables were collected in addition to an indication of what functions were performed. Directors were asked to rank eleven general functions in priority and to provide charts of the…
