Hierarchial causal models are described as pictorial representations of multiple regression equations. These models are particularly helpful for three reasons: (1) the formulation of problems in a path analytic framework forces a degree of explicitness that is often not present in research reports that rely solely on regression; (2) they provide a…

A study was conducted using the parity-equity model to investigate variances in faculty salaries at North Dakota State School for Science. The parity-equity model specifies three constructs as determinants of faculty salaries: (1) rational equity factors, including years of professional experience, rank, degree, graduate faculty status, tenure…

The relationship of multiple linear regression to various multivariate statistical techniques is discussed. The importance of the standardized partial regression coefficient (beta weight) in multiple linear regression as it is applied in path, factor, LISREL, and discriminant analyses is emphasized. The multivariate methods discussed in this paper…

A major concern of science educators is the lack of talented females selecting science careers. In spite of attempts during the past few decades to create equality in all facets of life in the United States, many sexual stereotypes persist. The research presented here is designed to examine the relationship of sex to the relevant factors…

Three models of multiple regression analysis (MRA): single equation, commonality analysis, and path analysis, were applied to longitudinal data from the Pennsylvania Vocational Development Study. Variables influencing weekly income of vocational education students one year after high school graduation were examined: grade point averages (grades…

A need to provide more data about the impact of schools on children in terms of manipulable variables prompted an examination of the relationship between school organization and student aspirations for further education. A causal model is examined which would enable investigation of the mechanism by which school contexts could alter aspiration.…

The purpose of this study is to investigate science achievement of Australian students and how this achievement can vary from school to school. The proposition that gender and socioeconomic inequities in Australia are the result of school systems designed to reproduce an unequal social order is be examined with reference both to current…
