This book on the growth of word meaning in children focuses on the development of the appreciation of the relations that exist among twenty selected words as the individual matures from childhood through adolescence to adulthood. The four preconceptions which determined the experimental tasks, the set of words used, and the methods of analysis…

The transferability, quality, and student perception of biology instruction at Metropolitan Campus, Cuyahoga Community College (Cleveland, Ohio) were the data sought in this joint study performed by the College's Department of Biology and the Office of Institutional Research and Studies. All Students who completed Biology 112 in the 1967-68…

The dissertation explores criteria for evaluating the performance of trigger mechanisms for determining extended benefit payment periods. A review of the current law is made as well as a brief summary of legislation leading to its passage. A quantitative model using concepts from the Theory of Markov Chains is established which meets established…

Press coverage of a suburban midwest school district is analyzed as a set of time series of observations including the amount and quality of coverage. Possible shifts in these series because of the emergence of controversial issues are analyzed statistically using the Integrated Moving Average Time Series Model. Evidence of significant shifts in…

The applicability of the Analysis of Variance, ANOVA, procedures to the analysis of dichotomous repeated measure data is described. The design models for which data were simulated in this investigation were chosen to represent simple cases of two experimental situations: situation one, in which subjects' responses to a single randomly selected set…

This is one of a series of eight short monographs intended to aid practicing educators in planning and conducting accountability programs in schools. This booklet discusses how to select a statistical technique that is appropriate to the objectives of a particular research or evaluation effort. Short sections focus in turn on classifying a study,…

Describes the renormalization group theory of second-order phase transitions suitable for undergraduate statistical physics. (Author/GA)

This is the first of a series of articles on the Vietnamese who have come to the U.S. since 1975. It deals with the making of the refugees and describes how the negative motivations and regrets with which they have come may act as obstacles to their adjustment to American life. (Author/GC)

Further explores the difficulties pertaining to limitations in the use and interpretation of the Index of Dissimilarity demonstrates some of the systematic biases resulting from these inadequacies and provides a mathematical refinement which overcomes some of the major problems inherent in the use of this index. (Author/AM)

This article proposes a method for testing equality of variances which exploits Pitman's idea and the computational power of simulations. Several advantages to this method are illustrated. A Monte Carlo study for several combinations of sample sizes and number of variables is presented. (Author/LMO)

Procedures are described for determining the statistical significance of a set of ratings made on bidirectional (B) scales. B and its statistical significance can be determined on samples of items or raters. The statistical significance of a mean of B values can be assessed by applying a normal approximation test. (Author/DWH)

A method requiring minimal computational effort is presented for transforming ordered residuals for purposes of testing the correctness of a regression model. The method maintains the same logical ordering in the transformed residuals as that of the original residuals and is suitable for either correlated or uncorrelated data. (Author/BS)

Commonly used techniques for estimating the effect of data error on fund allocations are biased because they fail to account for numerous sources of data error and for misspecification of the allocation formula itself. Alternate methods for estimating the effects of data error are presented. (Author/BS)

Decomposable models, which allow for the interdependence of structure among observable variables, are described. Each model is fully characterized by a set of conditional interdependence restrictions and can be visualized with an undirected as well as a special type of directed graph. (Author/JKS)

Approximations to the distribution of a common form of effect size are presented. Single sample tests, confidence interval formulation, tests of homogeneity, and pooling procedures are based on these approximations. Caveats are presented concerning statistical procedures as applied to sample effect sizes commonly used in meta-analysis. (Author)
