This study describes (a) potential mathematics education leaders' professional development experiences, awareness, beliefs, and attitudes and (b) the subsequent changes in these constructs as they participated in a leadership development program. The context of the professional development was a three-week institute and a year-long follow-up. The…

Offers a framework for remedying some of the problems associated with the use of statistical significance tests through modifying journal editorial policies. Reviews examples from some journals that have established guidelines for reporting results of statistical significance tests. (SLD)

Reports on a review of empirical research reports submitted over the past several years to the "American Journal of Distance Education" that identified common analytic problems and errors often overlooked by distance education researchers. Topics discussed include significance testing; assessment issues, including reliability and…

Discussion of automated indexing techniques focuses on ways to statistically document improvements in the development of an automated keywording system over time. The system developed by the Joint Chiefs of Staff to automate the storage, categorization, and retrieval of information from military exercises is explained, and performance measures are…

In an intervention aimed at showing students the amount of responsibility involved in caring for an infant, 353 predominantly ninth-grade and Latino students carried the Baby Think It Over simulation doll in an intervention and completed matched pre- and posttest measures. Statistically significant gains were found on the total score and the…

If we let all students at Ithaca College be our population, then our Office of Institutional Research can provide us with various parameters about this population. For example, we can obtain parameters regarding SAT scores, birth month, and GPA. Each student samples from the population and we compare their results to the parameters. This allows us…

The various costs of Type I and Type II errors of inference from data are discussed. Six methods for minimizing each error type are presented, which may be employed even after data collection for Type I and which minimizes Type II errors by a study design and analytical means combination. (Author/CM)

Demonstrates a statistically valid method allowing students to explore randomization. Described are two examples: counting techniques for a small set of data and simulation for a large sample. (YP)

Researchers have used many statistical models to determine whether an institution's faculty pay structure is equitable, with varying degrees of success. Little attention, however, has been given to court interpretations of statistical significance or to what variables courts have acknowledged should be used in an equity model. This article…

If risk taking is in some measure a signal to others by the person taking risks, the model of "costly signaling" predicts that the more the apparent cost of the risk to others exceeds the perceived cost of the risk to the risk taker, the more attractive that risk will be as a signal. One hundred and twelve visitors to youth…

This manual is a first effort to begin to identify, describe, and develop procedures for assessing various aspects of digital reference service. Its overall purpose is to improve the quality of digital reference services and assist librarians to design and implement better digital reference services. More specifically, its aim is to: assist…

This paper discusses the determination of college faculty salary inequity and identifies the areas in which human judgment must be used in order to conduct a statistical analysis of salary equity. In addition, it provides some informed guidelines for making those judgments. The paper provides a framework for selecting salary equity models, based…

The Workshop on Integrating Federal Statistics on Children provided a forum for assessing strengths and shortcomings of existing and proposed federal statistical data sources for children and families. In particular, these data sources were assessed with respect to their capacity to fill the most pressing information needs of those who formulate,…

The relationship between scores on the American College Test (ACT) and grade point averages of first-time college freshmen after the first year of study was investigated by correlating ACT composite scores and grade point averages (GPAs). ACT scores and GPAs were obtained for 100 first-time freshmen at an urban state university in Illinois. There…

Constructs a model that explains a large fraction of the variance in political science departmental rankings. Divides the objective predictors into two sets: one reflecting faculty quality ratings of department members, the other the effects of circumstances beyond a department's control. This model works well with most social science disciplines.…
