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…

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…

Two experiments investigated the acquisition of course material under conditions of repeated testing. In Experiment I, with limited study intervals, acquisition increased over trials of study followed by testing. In addition, adjunct information about the content of the test item pool also increased performance. In Experiment II, with student…

The definition, structures, utilities, stimulus-response differences, and portrayals of responsive evaluation are presented. An educational evaluation is said to be a "responsive evaluation" if it orients more directly to program activities than to program intents, if it responds to audience requirements for information, and if the different…

The area investigated in the present study is the comparison of the permutation t-test with Student's t-test and the Mann-Whitney U-test. The comparison was made for small samples for three distributions, including a normal distribution, a uniform distribution, and a skewed distribution. The properties of each test compared were the probability of…

The 1971 General Assembly and full board meetings of the International Council of Scientific Unions Abstracting Board (ICSU AB) were held in July at Orleans, France. This volume is the published proceedings of those meetings. The first part of the Proceedings is a detailed description of the activities of the Board. The second part records the…

Various ways of calculating the dissociation energies of pi bonds in alkenes are discussed. What seems to be the soundest values derive from isomerization kinetics. (Author/BB)
