Learning hierarchy research has been characterized by the use of ad hoc statistical procedures to determine the validity of postulated hierarchical connections. Various data sets are analyzed using a restricted maximum likelihood estimation procedure; results are compared with those obtained using the method suggested by Dayton and Macready.…

Statistical techniques for summarizing results from independent correlational studies are presented. The case in which only the sample correlation coefficients are available and the case in which the original paired data are available are both considered. (Author/JKS)

This article proposes several models for the analysis of mobility tables and examines the relationship of these latent structure models to some earlier mobility models, including the 'perfect' and the 'quasi-perfect' models. Uses of each of these models to derive various kinds of substantive inferences are suggested. (DB)

Methods for reviews of research that focus on inferring generalizations about substantive issues from a set of studies directly bearing on those issues are examined. The primary source of data was a content analysis of two samples of such reviews. (Author/RL)

An explicit statement of a statistic which is a nonparametric analog to one-way MANOVA is presented. The statistic is a multivariate extension of the nonparametric Kruskal-Wallis test (1952). In addition two post hoc procedures are developed and compared. (Author/JKS)

Examines the age distribution of injured workers relative to their exposure by industry and occupation; and looks at injury characteristics and costs associated with the age of the injured worker. Data indicate that occupational injuries occur at a lower rate to older workers than to younger ones. (CT)

Outlines Johnson's decision-making theory as a conceptual framework from which designers can work to facilitate effective relationships. The theory classifies clients into four styles: systematic internal, systematic external, spontaneous internal, and spontaneous external. (Author/JEG)

The Cuban Behavioral Identity Questionnaire is a short, eight-item questionnaire answerable in a seven-point Likert-scale format. It inquires as to the frequency with which respondents engage in several ethnic behaviors and the degree to which they are familiar with Cuban idiomatic expressions and Cuban artists/musicians. (Author/NQ)

Tells how data from readership surveys have been combined to create a decision model that provides newspaper editors with a systematic procedure for evaluating standard newspaper features; reports on a study that examined one set of subjective decisions a researcher is faced with when using the decision model. (GT)

Demonstrates how data analysis has been used in a number of recent court cases in the area of school finance. (Author/IRT)

Using data from Japanese, this article shows that the distinction between unergatives and unaccusatives is fully determined on the basis of the verb's inherent lexical meanings. (55 references) (Author/CK)

Data collection and analysis is often missing from the new curriculum reform textbooks. This article gives directions for data collection and data analysis for the Stroop Test and for a human-chain wrist experiment. (AIM)

Discusses substantive scale construction and the need for Rasch measurement practitioners to give careful consideration to designing variables based on theory, item construction, and models for the analysis of data. (SLD)

Describes a knowledge management system that was developed to help provide structure for dynamic and static data and to aid in the analysis of complex experimentation. Topics include quantitative and qualitative data; mining operations using artificial intelligence techniques; information architecture of the system; and transforming data into…

Discusses students' exploration of a particular rational function in the context of people waiting in line for service. The concepts of domain, range, and asymptotes are also developed in that context as is the effect of changes in input variables on function outputs. (Author/NB)
