The prediction that differences in incomes of high school and college graduates will not change is tested by applying standard statistical procedures to data describing actual income differences. Data from the United States Bureau of the Census describe annual incomes of men twenty-five years old and older during 1956-75. Report 1 displays results…

An analysis of measures used in assessment of innovation fidelity was studied. The purpose was to contribute to the development of valid and reliable methods of measuring critical elements of an innovation and identifying levels of implementation. Questionnaires were developed for high school introductory courses in English, calculus, and…

The effectiveness of schools and the levels of investment in schooling have been in question since the 1966 Coleman report "Equality of Educational Opportunity." Based on a theory of "knowledge-ability," this study challenges the assumption that given "inputs" will yield equivalent effects or "outputs." In…

Path analysis, a technique related to multiple regression analysis is used for ascribing causal relationships among variables. Path analysis involves the construction of explicitly formulated causal models and makes the reasoning explicit in the form of path diagrams and structural equations. Regression analysis is then used to construct path…

Least squares and Bayes methods were used in a cross validation study conducted for comparison purposes. The study applies to situations with the following conditions: predictor data are given on the same scales; criterion data may be given on different scales; and it is necessary to pool data even though criterion scale differences exist. Such a…

This statistical analysis of questionnaire data from a study of 673 third, fifth and seventh grade children and their parents was made to identify individual independent variables associated with children's total amount of television viewing. The data were analyzed by the stepwise linear regression method. The theoretical model guiding the…

Advantages of normalization regression estimation over ridge regression estimation are demonstrated by reference to Bloom's model of school learning. Theoretical concern centered on the structure of scholastic achievement at grade 10 in Canadian high schools. Data on 886 students were randomly sampled from the Carnegie Human Resources Data Bank.…

The purpose of the study was to determine the relationship between the quality of a supervised occupational experience (SOE) program (in terms of income and scope of program) and level of academic achievement on a test measuring technical knowledge in production agriculture. A fifty-item multiple choice achievement test was administered to…

The purpose of this study was to determine the degree of relationship between the effectiveness of the Instruction and Research Unit in the areas of instructional program (reading and mathematics), organizational operations (procedural and substantive), school-community relations, and staff development to several measures of student affective…

This study was initiated to investigate the relationship between voters' socioeconomic and attitudinal characteristics and their behavior in school district financial referenda. Using a survey instrument developed through pilot study application and factor analysis techniques, data were collected from 1,030 registered voters in three Kansas school…

This study sought to test by the validation process the finding that there is a different relationship between associative learning ability and IQ in middle- and low-socioeconomic groups as reported by Jensen and others. The study was conducted to ascertain need for revision of testing programs and curricular materials used with disadvantaged…

The purpose of this study was to develop the Johnson-Neyman Procedure (JN-Procedure) appropriate to multiple groups and covariables, and demonstrate its use in the analysis of group differences. A sequence of significance tests which makes it possible to identify the most parsimonious analysis of group differences appropriate to a given set of…

This paper offers a preliminary analysis of the effects of a semi-segregated school system on the IQ's of its students. The basic data consist of IQ scores for fourth, sixth, and eighth grades and associated environmental data obtained from their school records. A statistical model is developed to analyze longitudinal data when both process error…

This study is a cross-section regression analysis of male-female wage differentials in urban labor markets. Data for the study were obtained from the 1967 Survey of Economic Opportunity. A prime objective of this dissertation is to determine how much of the observed male-female wage differential can be attributed to the effects of discrimination…

Criteria and methods for developing a taxonomy for different situational categories are presented. (CK)
