In many situations in education and psychology it is desired to select from k binomial populations the one having the largest probability of success. This paper describes a two-stage procedure for accomplishing this goal. (Author/CTM)

When analyzing a squared multiple correlation coefficient, an investigator may be interested in determining whether it is above or below a known constant, rather than testing the null hypothesis. This paper gives the sample sizes required for answering this question when indifference zone formulation of the problem is used. (Author/BW)

The Statistical Analysis System was used to program a statistical procedure developed by K. J. Levy (1975). The focus was on Dunnett-like pairwise multiple comparisons among sample variances. An example using data from G. Glass and K. Hopkins (1996) is used to illustrate a computer run with this program. (Author/SLD)

Focuses on meta-analysis in educational research. Contends that, if significant meta-analysis results are overrepresented through selective sampling, hucksterism in form of sampling bias exists. Explains use of follow-up test, the fail-safe N. Includes tables constructed to assist researchers and practitioners to estimate, without calculation,…

Standard Microsoft Excel functions and the Excel Data Table facility are used in randomization applications using resampling with and without replacement.

Engaging students in worthwhile learning requires more than a knowledge of underlying principles of good teaching. It demands considerable practice as well as images of what good teaching in particular situations and for particular purposes might look like. This volume provides these images. These cases were written from authentic, unrehearsed…

The Longitudinal Surveys of Australian Youth (LSAY) is a research program that tracks young people as they move from school into further study, work and other destinations. This "User guide" has been developed for users of the LSAY data. The guide endeavours to consolidate existing technical documentation and other relevant information…

This report uses data from the Pre-Elementary Education Longitudinal Study (PEELS) to describe access for young children with disabilities in two specific domains: community activities, including extracurricular activities and family recreation, and kindergarten classroom experiences. While PEELS is a broad, descriptive study, the analyses…

In this set of four supplemental tables, the authors compare the baseline test scores of the treatment and matched control group samples observed in each year after KIPP entry (outcome years 1 to 4). As discussed in Chapter III, the authors used an iterative propensity score estimation procedure to calculate each student's probability of entering…

Recent work has demonstrated that many offenders will choose to serve prison rather than any amount of a community-based sanction. This primarily quantitative research has found that offender-generated exchange rates are influenced by a wide variety of experiences and characteristics. Missing from this literature is a qualitative evaluation of…

Developmental trajectories provide the empirical foundation for theories about change processes during development. However, the ability to distinguish among alternative trajectories depends on how frequently observations are sampled. This study used real behavioral data, with real patterns of variability, to examine the effects of sampling at…

The purpose of this study is to examine the effects of reflective counseling group supervision (RCGS) for military counselors. A convenience sampling method is adopted. Twenty-two military counselors participate in this study. Both qualitative and quantitative research methods are used for collecting and analyzing data. The results support our…

Multiple regression is commonly used in social and behavioral data analysis. In multiple regression contexts, researchers are very often interested in determining the "best" predictors in the analysis. This focus may stem from a need to identify those predictors that are supportive of theory. Alternatively, the researcher may simply be interested…

Context: There is growing concern about illicit rural stimulant use, especially regarding methamphetamine use and its health consequences. Purpose: The present study describes associations between aspects of stimulant use and illness experience in rural areas, with additional focus on the role of demographic characteristics in these associations.…

We describe an automatic classroom capture system that detects and records significant (stable) points in lectures by sampling and analyzing a sequence of screen capture frames from a PC used for presentations, application demonstrations, etc. The system uses visual inspection techniques to scan the screen capture stream to identify points to…
