Four potential biases incurred by using a sample of wives of male respondents as a sample of women for sex comparisons of the occupational attainment process were examined and empirically assessed. Using data from the Wisconsin longitudinal study of high school seniors, the extent and nature of two potential biases were considered: (1) a sampling…

The effects of racism and sexism can be seen in the various elements of research methods including the selection of topics, design, sampling, measurement, and the generation of conclusions. In selecting topics, potential sources of bias such as funding sources and publishing patterns are covered. How knowledge of appropriate literature, selection…

This report focuses on two separate aspects of the longitudinal study of innovative instruction called Studies of Innovation. These aspects are the innovation being studied (the Instructional Programming Model of the Individually Guided Education Program) and the procedures used in selecting research sites. Following the introduction, Chapter 2…

Twenty-three male distance runners between the ages of 16 and 23 who had achieved a ten-minute or better two-mile performance were tested to determine physical and physiological characteristics to be used in predictive research regarding running performance. Relative body fat ratio, metabolic data, and oxygen intake capability were among the…

The amount of variance accounted for by treatment can be estimated with omega squared or with the squared multiple correlation coefficient. Monte Carlo methods were employed to compare omega squared, the squared multiple correlation coefficient, and the squared multiple correlation coefficient to which a shrinkage formula had been applied, in…

The U.S. Army Research Institute for the Behavioral and Social Sciences has developed a wide range of statistical models to test hypotheses generated in relation to an equally wide range of measurement and evaluation situations. The randomized block (RB) design has traditionally been a preferred model for much psychological research. The RB has…

Using "Books for College Libraries" as a standard reference against which to compare the Purdue University Calumet Campus library collection, a quantitative analysis of the library's holdings in various subject areas was done during the 1973-74 academic year. For each of the 65 subject areas selected, randomly chosen entries in…

A computer-simulated study was made of the sampling distribution of omega squared, a measure of strength of relationship in multivariate analysis of variance which had earlier been proposed by the author. It was found that this measure was highly positively biased when the number of variables is large and the sample size is small. A correction…

One of six summaries of workshop sessions (See TM 000 130), designed to strengthen the evaluation of costly programs and their effects, this handbook presents an analysis of both random and nonrandom sampling errors by application of the Bayesian model. This model attempts to formalize the process and procedures of inference from data through…

Methods for designing and conducting research related to health education, physical education and reaction are described. The use of libraries, the selection and definition of research problems, principles of statistically sampling, and data collection devices are presented. Instructions for the construction and validation of tests as well as…

In any field of study, teaching and learning go hand in hand with testing. In foreign language teaching, the testing of skills development has become a specialized area requiring the combined efforts of linguists, psychologists, statisticians, and educators. Teachers must constantly ask: What kind of progress are my students making in this second…

This document is a manual of instruction on how to administer the Child Behavior Survey Instrument (CBSI). This manual also presents definitions of the categories used to define the nature of the observed child's behavior. The CBSI provides a scheme for observing the classroom behavior of children along nine major categories: (1) orientation, (2)…

Two relatively new tools for analysis of data compiled in evaluation studies are presented. The National Test-Equating Study in Reading, known as the Anchor Test Study, produced tables of score-correspondence between the eight reading comprehension and vocabulary tests most widely used in the United States. Two types of tables from this report…
