An historical analysis is presented of the controversy surrounding an alleged study, the data from which were originally published in 1969. Despite considerable evidence refuting the validity of both the data and the study, the results continue to be cited in school psychology literature. (Author)

A review of the literature suggests that no significant research has been conducted with adolescents with educational handicaps in the areas of achievement motivation, labeling, memory and retrieval, moral development, and cognitive development and integration. (Author)

Presents eight assumptions to help people understand quantification not only as it is traditionally approached--as a method of measuring reality--but also as a method of shaping reality. The categories we use in creating statistics change the way we perceive the world. (Author/IRT)

Valid statistical tests for one-subject experiments are necessary to justify statistical inferences and to ensure the acceptability of research reports to a wide range of journals and readers. The validity of randomization tests for one-subject experiments is examined. (See TM 505 800-801).(Author/JKS)

Two types of problems supposedly associated with the use of randomization tests for single-subject experiments have been discussed: the random introduction of treatments and the repeated alternation of treatments. Ways to reduce the adverse effects associated with these problems are presented. (See TM 505 799-800). (Author/JKS) (Author/JKS)

A simple example is presented that illustrates advantages of Bayesian and likelihood methods of inference relative to sampling distribution methods of inference. It is argued that Bayesian and likelihood methods of inference should be utilized more generally to analyze real data. (Author/CTM)

Presents statistics for 1976 concerning the production of fossil fuels throughout the world. (MLH)

Periodical prices by subject field. (LS)

Presents the 1997 U.S. Periodical Price Index sponsored by the Library Materials Price Index Committee of the Association for Library Collections and Technical Services, a division of the American Library Association. Finds that the average price increased 9.9%, .9% below 1996's rate. Includes seven tables, a chart, and a summary sheet. (PEN)

META-RAND, a Statistical Analysis System macro that generates random values used for calculating correlations in a meta analysis, is described. Output consists of uncorrected and corrected mean and variances of "r" and several measures of the degree of homogeneity or heterogeneity in the data. (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 reports on studies of the deterministic and stochastic behaviours of a predator-prey system with prey-dependent response function. The first part of the paper deals with the deterministic analysis of uniform boundedness, permanence, stability and bifurcation. In the second part the reproductive and mortality factors of the prey and…

This article describes a simple way to explain the limitations of statistics to scientists and students to avoid the publication of misleading conclusions. Biologists examine their results extremely critically and carefully choose the appropriate analytic methods depending on their scientific objectives. However, no such close attention is usually…

Longitudinal data analyses can be usefully supplemented by the plotting of individual growth curves. Unfortunately, such graphics can be challenging and tedious to produce. This article presents and demonstrates a SAS macro designed to automate this task. The OLStraj macro graphically depicts ordinary least squares (OLS)-estimated individual…
