Notes that researchers are often required to examine specific model under two different situations. Cites studies in which authors compared results descriptively without use of inferential statistics. Describes use of series of regression tests to compare two situations statistically. Gives example from recent study to illustrate technique.…

Notes that conventional statistical models are not suited for analysis of nonindependent observations produced by family systems. Demonstrates how structural equation modeling enables the study of family processes in a way that is consistent with a systems perspective. Uses analysis of perceived coerciveness in two-parent, two-child families to…

Discusses problems in analyzing change in nonexperimental data. Tests three ordinary least-squares regression models to illustrate similarities/differences. Notes that model based on raw difference change scores applies best to studying change processes; model based on outcome scores applies best to assessing consequences of change; and model…

Discusses analysis of covariance (ANCOVA), a standard tool for data analysis in psychological research. Considers the two major ways in which psychologists have used the technique: for increasing the precision of estimation in randomized experiments and for seeking to remove bias in nonrandomized studies, comparing ANCOVA with analytic…

Defines structural equation modeling as comprehensive, flexible approach to research design and data analysis. Provides conceptual overview of clinical research hypotheses that invite evaluation as structural equation models. Particular attention is devoted to hypotheses that are not adequately evaluated using traditional statistical models.…

Reexamined previous statistical comparisons of two models for adolescent drug abuse using new statistical estimation methods in causal modeling not requiring assumptions about normally distributed variables. An asymptotically distribution free method shows that the models fit even better than assumed in the initial work. (Author/JAC)

Tested models of interests by examining the significance of disconfirmed ordinal predictions. Examined data regarding Holland's hexagonal model and Roe's circular ordering. Tested adequacy of the hierarchical model and compared significance of the disconfirmed predictions of the hierachical model to that of the hexagonal-circular model. (Author)

With the development of refined theory and increased measurement sophistication in family research, multidimensional concepts and multiple indicators are appearing in the literature. This paper provides a nonmathematical introduction to canonical correlation analysis and three empirical examples that demonstrate the technique's applicability in…

To establish a sophisticated planning mechanism that will translate readily to affordable tactical steps, university planners must have a good understanding of the cost structure of individual academic and administrative departments and of the efficiency and effectiveness of the staffs of those departments.

Presents an opinion survey developed to assess residence hall students' opinions and as a model of comprehensive student-based research. Discusses random sample selection, survey implementation, and data analysis. Results of the survey indicated significant sex differences in attitudes about resident assistants, housekeeping, and drinking. (RC)

The Judicial Evaluation Method (JEM) is useful for aiding decision-making bodies to formulate policies. Broad public participation in complex issues is provided by JEM. (The conceptualization, policy formulation stages, and participant roles are identified; and the model is applied in two case studies). (MH)

This document, one in a series developed to provide technical assistance to 22 Long-Term Care Gerontology Centers, addresses the application of evaluation procedures within centers and their component programs and projects, including: (1) interdisciplinary education and training; (2) service and practice model development; (3) research; (4)…

Relevant conceptual frameworks must guide data collection and analysis if data are to be useful to service program planners and administrators. Such frameworks are increasingly important in the systematic assessment of the total array of services in a planning region. This paper describes a two-dimensional classification matrix developed in…

Title I Evaluation models using uniform procedures and data collection for state and national comparisons are interpreted as federal endorsement of basic, common competencies in reading and mathematics. Basic competencies, content homogeneity, conversion methodology, and validity of the evaluation are discussed. (MH)
