Factor analysis is often neglected in survey research, despite the fact that it removes metric redundancies and extracts the common thread from a set of observed variables. Likert-based extension surveys would benefit from factor analysis. (SK)

Suggests that performance measurement data already being collected could become more useful, at low additional cost, by further analyzing the relationships among the measures, especially across time. Using logic models and analyzing variability among program delivery units could provide evidence for hypothesized connections among delivery,…

Describes two methods commonly used to calculate achievement gaps and suggests problems in the calculation of achievement gaps. One method uses percentage points as a form of "common currency"; the other calculates the change over time in proportion to the figures that are changing. Discusses reasons the second method may be preferable. (SLD)

Develops a bibliometric profile of four information science journals; analyzes data on acknowledgments to funding sources, authors' nationalities, and the citedness of published articles; and explores the relationships among these variables. Citedness appears to be associated with journal of publication and an author's nationality, but not with…

Studied the analytic problems associated with a design in which one identifiable group is allocated to each treatment condition and members of these groups are measured to assess the intervention. Results from a simulation study underscore the analytic problems associated with these quasi-experimental or group-randomized designs. (SLD)

Fully and partially ranked data arise in a variety of contexts. From a Bayesian perspective, attention has focused on distance-based models; in particular, the Mallows model and extensions thereof. In this paper, a class of prior distributions, the "Binary Tree," is developed on the symmetric group. The attractive features of the class are: it…

This paper focuses on the data analysis stage of phenomenographic research, elucidating what is involved in terms of both commonality and variation in accepted practice. The analysis stage of phenomenographic research is often not well understood. This paper helps to clarify the process, initially by collecting together in one location the more…

The state of the psychotherapy termination literature to date might best be characterized as inconclusive. Despite decades of studies, almost no predictors of premature termination have emerged consistently. An examination of this literature reveals a number of recurrent methodological-analytical problems that likely have contributed substantially…

This article examines the impact of racial consciousness on the practice of a group of five exemplary teachers, participants in a long-term professional development program in diversity education. The article draws from transcripts of group discussions in which teachers reflect on the development of their consciousness of race, racism, and…

To date, finite mixtures of structural equation models (SEMMs) have been developed and applied almost exclusively for the purpose of providing model-based cluster analyses. This type of analysis constitutes a direct application of the model wherein the estimated component distributions of the latent classes are thought to represent the…

The purpose of this paper is to examine the possibility of measuring efficiency in the context of higher education. The paper begins by exploring the advantages and drawbacks of the various methods for measuring efficiency in the higher education context. The ease with which data envelopment analysis (DEA) can handle multiple inputs and multiple…

This study examined how the cumulative (additive) versus differential (individual) effects of trauma influenced male delinquency. Using a comprehensive measure of trauma, a secondary data analysis was conducted on a nationally representative sample of male youths between the ages of 12 and 17. Logistic regression analyses revealed that all three…

In speech research, it is often desirable to assess quantitatively the variability of a set of speech movement trajectories. This problem is studied here using synthetic trajectories, which consist of a common pattern and terms representing amplitude and phase variability. The results show that a technique for temporal alignment of the records…

This paper presents a critical analysis of data analysis requirements in physics tertiary entrance examinations. The setting is Western Australia. Common aspects of the questions asked over 14 years and changes in the questions since a major syllabus reform are identified. Similar changes in other jurisdictions are referenced. The data analysis…

We address whether the relationship between education and health can be interpreted causally. Alternatively, both may be determined by common unobserved factors such as individual time preferences. We add to the primarily US-based evidence by using a Danish panel data set of employed persons, and use Danish school reforms to instrument education…
