Many researchers assume that unequal cell frequencies in analysis of variance (ANOVA) designs result from poor planning. However, there are several valid reasons why one might have to analyze an unequal-n data matrix. The present study reviewed four categories of methods for treating unequal-n matrices by ANOVA: (a) unaltered data (least-squares…

While the logic of science serves as the methodological framework for psychological research, its particular merit for educational evaluation has yet to filter into practical application. The logic of science provides a strategy for evaluating large and complex educational treatments that is a useful guide to program development and improvement.…

This thesis provides evidence for the existence of a creativity dimension containing figural and verbal subfactors which is independent of intelligence and marginally related to school achievement. The original data of Wallach and Kogan, as well as the data from the Ward, Cropley and Maslany and Wallach and Wing studies were reanalyzed using…

A comprehensive overview of purpose and content of the Program (an opportunity for Federal executives to learn first-hand about United States Congress in operation through work assignments with members of Congress and staffs of Congressional committees) and a report of reactions of participants to the Program is presented. Information for analysis…

The results of a meeting of the Toronto Board of Education are given. Basically, a special program for students was examined. Two kinds of data were used to assess school achievement: school marks and reading test scores. Students in the special program were matched with students who met the following criteria: (1) came from the same senior…

Piaget explains the stage IV error as a failure to assimilate the new place of hiding rather than a forgetting of it. His hypothesis predicts that the likelihood of error should not vary with the length of the delay interval. Nine-month-old infants delayed 0, 1, 3, or 7 seconds before having the opportunity to search. Infants in all conditions,…

A major problem encountered by both teachers and authors of instructional materials is the sequencing of instructional activities. A review of the literature is given and it is pointed out that there is substantial evidence to support the general theory of the hierarchical structure of knowledge. A learning hierarchy for the computational skills…

A random sample of 60 ninth grade students from each of four schools in suburban areas of Chicago was obtained to ascertain student interest in vocational education, more specifically in applied biological and agricultural occupations, by means of a Career Interest Inventory. Mean item scores were obtained in order to make a comparison between…

This paper provides a survey of models for the analysis of individual growth data emphasizing the problems posed by serial or time dependence in the application of polynomial regression models. The concepts of serial correlation and autoregressive models are illustrated. It is demonstrated that standard inference procedures may be quite misleading…

This is the second of four reports representing an effort to develop a system of indicators of scientific technical information. This particular report is concerned with the data analyses which led to the system of statistical indicators described in the first report. It includes a discussion of the overall framework upon which the study was based…

The purpose of this paper is to examine adolescents' shifts in orientations toward and respect for their friends, mothers and fathers from the 7th through the 12th grades. (Author)

What line managers want most from trainers is proof of a training investment pay-off, and techniques are offered to help trainers measure the organizational return on training. (Author/AJ)

The problem lies more in the proper use of standardized tests in decision-making than in the tests themselves. (Author)

Global Environmental Monitoring System (GEMS), the global environmental monitoring system of the United Nations, aims to assess conditions on planet Earth by establishing a global system of data gathering and monitoring. Projects dealing with the oceans, atmosphere, human health, and renewable natural resources are discussed. (BT)

Suggests that because of deficiencies in the statistical analysis and errors of inference, neither the conclusions nor the policy recommencations derived by Coleman are well supported. (Author/AM)
