This paper makes the point that descriptive and inferential measures of nonnormality and graphic displays of the frequency distribution of important variables should be routine in research reporting. This point is particularly true for research involving measures with nonarbitrary metrics where the distribution shape is unaffected by measurement…

Discusses ways to use bar charts and line graphs to present comparative information in a flexible manner. Includes activities designed to review how the different characteristics of charts and graphs relate to different document structures. (RS)

Describes ways for school newspapers and yearbooks to better communicate through "infographics" (a graphic representation of primarily statistical data that helps to tell the story). (RS)

Argues that graphs and charts are cases of document structures introduced in previous columns: combined lists, intersecting lists, and nested lists. Explores pie charts and various aspects of bar charts as they relate to other document structures presented in this series. (RS)

Offers guidelines summarizing the major points of judges in the 1989 Yearbook Excellence Contest regarding: (1) visual impact; (2) visual readability; (3) appropriateness of illustrations and graphics to the verbal content; and (4) writing quality. (SR)

Examines the structure of titles in Spanish. These structures have a sealed character with respect to the extraction of their constituent parts. Certain instances in which this generalization appears not to be followed are analyzed, and it is shown that the extraction is a verb rather than a noun form. (15 references) (Author/CK)

Structural models that yield circumplex inequality patterns are reviewed, focusing on a model developed by T. W. Anderson (1960). A modification is proposed to this model to allow for negative correlations. This model may be reparameterized as a factor analysis model with nonlinear constraints on the factor loadings. (SLD)

The distance approach to nonlinear multivariate analysis proposed by J. J. Meulman (1986) is reviewed. Several generalizations are discussed by combining features from the conventional multivariate analysis approach, which seeks weighted sums of variables, with the alternative approach, which seeks to fit distances. (SLD)

This explanation of how the basic economic model of pricing applies to the CD-ROM industry considers the supply and demand sides of the market and compares three distinct pricing strategies: (1) pricing to maximize profits; (2) average cost pricing; and (3) marginal cost pricing. (EAM)

Reports on the validity of the Multiple Poisson (nP) model of word distribution in full-text document collections. A practical algorithm for determining whether a certain word is distributed according to an nP distribution and the results of a test of this algorithm in three different document collections are described. (14 references) (KRN)

A model for the age standardization of test scores is presented, which is fitted to the percentile points of the raw score distribution and assumes a linear trend of each percentile with age. The model's applications in standardizing tests and diagnostic plots produced by a computer program--STANEW--are described. (SLD)

Describes a simple demonstration in which students toss crumpled paper on opposite sides of a classroom and graph the results in order to demonstrate dynamic equilibrium. (WRM)

Provides activities that support students as they develop their intuitive notions of graphs. Activities help students describe the relationships expressed in the graphs and make generalizations about inferences on the basis of the visual image. (ASK)

Discusses the use of Calculator Based Ranger (CBR) in mathematics classrooms. Provides a classroom activity in which students graph walking in different directions and speeds. Presents student work and testing. (ASK)

Presents a model for representing and storing binary topological and directional relationships between 2-dimensional objects that is used to provide a basis for fuzzy querying capabilities. A data structure called an abstract spatial graph (ASG) is defined for the binary relationships that maintains all necessary information regarding topology and…
