A study of the "efficiency and efficacy" of evaluation practices of the Illinois Division of Vocational and Technical Education as conducted by Educational Testing Service is reported on. The study was directed toward understanding how evaluation practices of the Division, with largest emphasis upon the performance of the Three Phase System used…

This report presents considerations for sample design and estimation procedures for the Health Examination Survey, one of the major survey programs employed by the National Center for Health Statistics. The survey collects data which provide national estimates and distributions of various health characteristics related to the growth and…

In an attempt to improve the economic well-being of the disadvantaged, this study investigated the possibility that excessive hiring requirements might be a major factor in unemployment of particular groups in the population. This was accomplished by surveying a random sample of employers in 10 major entry and near-entry level occupations in the…

This evaluation report on the Green Thumb program is the first in a series of three reports that will constitute a comprehensive evaluation of Operation Mainstream (OM). Operation Mainstream is a collection of programs designed to employ as enrollees poor, chronically unemployed adults. This evaluation relies primarily on cross-sectional and…

This study was designed to assess the conceptual structure of the Task of Public Education Opinionnaire (TPE). Since the development of the instrument, several psychometric techniques have been formulated. Two of those methods, image component and alpha factor analysis, were applied to the items of the TPE after the correlation matrices were…

A second-year interim report on a three-year cooperative study involving a regional sampling of 41 Kentucky school districts is presented. The ultimate goal of the project is to develop methods of sampling and annually assessing the extent of learners' needs and to stimulate educational programming based on the reduction of learners' needs. Major…

A subject by item matrix of test responses is shown to be a useful heuristic in criterion referenced and norm referenced test analysis, and in the teaching of measurement. The pattern of responses within the matrix provides indications of item interactions, weak deceptors, and conventional test statistics. The strong visual analogy between the…

An experimental study of the efficiency of human information processing is based on the Bayesian model for simple hypothesis testing with fixed binomial sampling. Each of 60 subjects is analyzed with separate ANOVAs focusing on two efficiency variables. Sample size and critical value are also analyzed. Subjects show very different utilization of…

The purpose of this study was to generate descriptive statistical estimates regarding the expected proportion of occurrence of each of the PROANA 5 (Process Analysis) variables (line usage, clique group, detrimental clique group, leadership, and dominance) in small group communication. A second purpose was to determine the expected pattern of…

This paper begins with a brief review of research trends in the area of organization and memory. A discussion in them presented their relevance to the study of children's processing abilities, and the suggestion is presented of a possible useful tool in the application of knowledge about information processing to the educational experience of the…

Five three-variable combinations were obtained from a variety of standardized test scores of 331 male children. These five groups were treated as unrestricted populations of the case III variety. Extreme univariate selection was produced in each group allowing for tests of differences between the correlation values of the two incidental variables…

A test of mental arithmetic skills was developed and normed for children in grades one to six. Statistical techniques were used to predict the probability correct for each item and to rank order the items. Students in a given grade took only one level of the test and inferences were made of their performance on those tests which they did not take.…

The Cost and Funding Studies project of the proposed Western Interstate Bibliographic Network began activities in July 1975. The goals of the project were to: (1) determine representative costs of present library services in the West, (2) estimate future costs of library services in the West with proposed network support, (3) evaluate and compare…

The unbiased estimate of a "treatment effect" reached by analysis of covariance in a nonrandomized experiment would often require that a different covariate be used in each treatment. A sufficient but unlikely condition for an unbiased estimate is that the covariate for each treatment is (1) the complete covariate that predicts the outcome as…

The optimum weighting of variables to predict a dependent-criterion variable is an important problem in nearly all of the social and natural sciences. Although the predominant method, multiple regression analysis (MR), yields optimum weights for the sample at hand, these weights are not generally optimum in the population from which the sample was…
