Using the notion of parallel items this paper presents a family of new criteria for cluster analysis. (Author)

This study presents the results of statistical use in the field of communication as evidenced by the research published in the last two years of the Journal of Communication. (Author/RK)

The randomized response model described in this study works against the types of bias which make faculty evaluation surveys unreliable. (Authors/CB)

Authors conclude that, in the world of real data sample correlation matrices, Guttman's stronger lower bound is not of practical use in determining the effective number of common factors. (Authors/CB)

Author discusses the implications that criterion-referenced tests have for the teacher and for testing programs in the schools. (Author/CB)

Students learn to understand the environment and discover the world of tiny creatures beneath their feet. (RK)

Authors present a formula for use when restrictions result from complex or unmeasured variables. (Authors/MB)

Relations between standard statistical techniques for analyzing dichotomous data and ANOVA procedures are indicated. The need for usefulness of analyzing transformed data as opposed to direct analysis of dichotomous data are discussed. Required statistical procedures employing transformed data are outlined.

Describes the use of capture-recapture techniques to estimate the population of taxis in Liverpool and demonstrates the points of similarity to animal population estimation. Considers advantages of studying taxis rather than organisms in introductory studies of the techniques. (AL)

In a study of teacher role, the collection of data from a sample of teachers in the United States, Britain, Australia, and New Zealand is described, and the techniques used to analyze the data are discussed. (DB)

Data from infants unable to complete experimental sessions were compared to those for whom there were complete data. Results suggest that the elimination of large numbers of infants may have a potentially biasing effect on reported data. (Authors)

Much of educational administration research suffers from lack of conformity between data analysis and research design, inattention to the test/retest stability of measurement instruments, and the use of statistics for nominal or interval data with ordinal data, random-sample statistics with nonrandom samples, and unnecessarily complex statistical…

Sternberg (1981) presented correlations based on independent samples of about 25 cases each with a statistical comparison in a population parameter of zero and interpreted his results as if with appropriate tests. He needed to use a nonzero population parameter and compare for the difference between the z transformations. (Author/CM)
