As students are asked to share more of the costs of a post-secondary education, the quality of their overall educational experience and perceived return on investment (ROI) are increasingly important. For prospective students and their parents, what they are told they can expect from the student experience at an institution often makes the most…

SNAP/SHOT (System Network Analysis Program-Simulated Host Overview Technique) is a discrete simulation of a network and/or host model available through IBM at the Raleigh System Center. The simulator provides an analysis of a total IBM Communications System. Input data must be obtained from RMF, SMF, and the CICS Analyzer to determine the existing…

Hierarchical data analyses in different discipline areas are reviewed in this article to compare statistical applications between the Hierarchical Linear Model (HLM) software and the Statistical Analysis System (SAS) MIXED procedure. Similar features of the two software programs are illustrated through reconfirmation of an HLM example using the…

The major objective of this paper was to demonstrate that it is possible, using a probabilistic approach, to derive a method of evaluating the interaction of adverse effect, criterion differences, and bias and, using a linear model, determining their effect on job relatedness. (Author)

Many higher education institutions are focusing on their admissions operations. They are attempting to ensure a steady stream of enrolling students, and/or attempting to ensure the quality or composition of their entering classes. However, many colleges have not developed a comprehensive method of tracking student cohorts, measuring retention, and…

Twenty per cent of 8400 questionnaires distributed in 1977 to a representative sampling of public libraries throughout Massachusetts were returned and analyzed. Those returned were entirely representative of the state's population and of the size of library services represented, although communities with the most "active" library…

To prepare the education chapter for the forthcoming volume of the U.S. Library of Congress'"Handbook of Latin American Studies," the author reviewed over 500 publications on Latin American education issued between 1978 and 1983; the abstracts of approximately 200 of them will be published in the forthcoming volume of the Handbook. The…

This paper illustrates how canonical correlation analysis can be employed to implement all the parametric tests that canonical methods subsume as special cases. The point is heuristic: all analyses are correlational, all apply weights to measured variables to create synthetic variables, and all yield effect sizes analogous to "r"…

This paper identifies specific problems with stepwise regression, notes criticisms of stepwise methods by statisticians, suggests appropriate ways in which stepwise procedures can be used, and gives examples of how this can be done. Although the stepwise method has been routinely criticized by statisticians, it is still frequently used in the…

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…

In the late 1960's, educators and researchers became concerned with the dropout problem in large urban school districts. In Philadelphia, the Division of Pupil Personnel and Counseling (PPC) is responsible for collection of this data and reports this information to the state. The process has been computerized to cope with the large volume of data.…

The use of repeated measures research designs is explored. Repeated measures designs are often advantageous and can be implemented in a variety of research settings. One of the main advantages in repeated measures designs is the control of subject variability. Other advantages are the reduction of error variance and economy in subject recruitment.…

This paper reviews the literature on methods for dealing with missing data, discusses four commonly used methods, and illustrates these approaches with a small hypothetical data set. Most studies contain some missing data, and the reasons data are missing are many and varied. Four commonly used methods have been identified in the literature: (1)…

In March 1996, the Region XI Education Service Center, Fort Worth (Texas), was designated to continue a project implemented in 1990 by the Texas Education Agency to study the overall effectiveness of special education programs. The 1996 project was extended in 1997. This paper reports on the first of three newly planned study components, the…

The accuracy with which regression models estimate treatment effects is dependent upon a number of conditions. The stability of the regression line (a function of sample size and correlation between pretest and posttest) is said to be the most important of these conditions. The utility of regression models is proportional to the size of the…
