Pearson's unrestricted chi-square procedure is reviewed, and an historical presentation of Neyman's restricted chi-square test is introduced with a discussion of its theory and applicability to education. An example of the Neyman procedure is discussed in detail to familiarize researchers with this useful technique for analyzing contingency…

Under some circumstances, it is desirable to compare the factor patterns obtained from different factor analyses. To date, the best method of simultaneously achieving simple structure and maximum similarity is the technique devised by Bloxom (1968). This technique simultaneously rotates different factor patterns to maximum similarity and varimax…

Three topics in factor analysis are covered: a) a reliability coefficient for assessing the quality of a maximum likelihood factor analysis, b) an application of three-mode factor analysis to serial learning data, showing variations in learning curves over stages of learning and individuals, and c) the use of personal probability functions to…

This paper is concerned with the study of similarities and differences in factor structures between different groups. A common situation is when a battery of tests has been administered to samples of examinees from several populations. A very general model is presented, in which any parameter in the factor analysis models (factor loadings, factor…

This study tests the appropriateness of Torrance's assumptions of trait independence and the combinability of measures (Torrance Tests of Creative Thinking) with respect to the scoring of the tests for a younger population and estimates the homogeneity of the scores. The sample consisted of 128 elementary school children. Results indicate that…

Besides the ubiquitous Pearson product-moment r, there are a number of other measures of relationship that are attenuated by errors of measurement and for which the relationship between true measures can be estimated. Among these are the correlation ratio (eta squared), Kelley's unbiased correlation ratio (epsilon squared), Hays' omega squared,…

Conventional methods used for the presentation of pre- and post statistical information generally are deficient in economy and compactness and fail to show internal movement from pre- to posttest. This technique precludes these shortcomings through the presentation of information in a highly visible manner which reveals the strata of internal…

A total of 18,740 psychiatrists and psychiatric residents (trainees) were identified in the U.S. in 1965, and survey data were obtained from 16,449 respondents (88 percent). The data are presented here as: (1) characteristics of the supply: sex, age, citizenship, work status (full time, part time, etc.), and primary and secondary subfields of…

To test the "stoop labor" hypotheses that the supply response of domestic migrants to increased wages would be inelastic, this study examined wage adjustment in Michigan agriculture after 1964, supply response to wage changes in the pickle industry, and acreage decline and capital substitution following the termination of the bracero…

The mathematical models of this paper were developed as an outgrowth of working with the Comprehensive Achievement Monitoring project (Project CAM) which was conceived as a model and application of sampling procedures such as those used in industrial quality control techniques to educational measurement. This paper explores mathematical modeling…

The intent of this study was to describe low-wage, low-skill workers within the context of their work environment and to develop techniques to measure the effects of Skill Advancement's skill training program on the participants. Due to the lack of research findings in this area, these research efforts were somewhat exploratory in nature,…

The purpose of this research is to evaluate the effectiveness of the area (homogeneous) scales of the Navy Vocational Interest Inventory (NVII) as predictors of Class "A" school achievement and as measures of rating differentiation by comparing specific occupational scales with more general interest measures--the NVII area scales. The…

This study is part of a program designed to attempt identification of dissonance through components of electrophysiological instrumentation, for measuring and presenting to a person some of his own unconscious dissonance, of which he is normally unaware. Using college students as subjects, the authors used attitude ratings on values to attempt to…

A statistical analysis of the effect of television commercials on children, this study found that children both like and believe television commercials. Middle Western children from grades two through five rated four videotaped TV commercials, selected at random, on a scale of true/false, happy/not happy, real/not real, stupid/smart, nice/not…

This paper investigated the assumption that a linear relationship could be detected between the process of source credibility evaluation and the seeking of information. The authors utilized twelve semantic differential scales which, when used for evaluating the source credibility of public figures, clustered into four dimensions: competence,…
