Research on the effectiveness of graphical displays for information acquisition and retention lacks a system for classifying graph information and generating test items to assess learning. The purpose of this study was to validate a system based on two types of information and three types of informational units. Results of an analysis of variance…

Florida's urbanized rural population consists of 3 segments: persons in places under 2,500 population; persons in suburbs or open country but not on farms; and persons in other urban territory. This urbanized rural population continues to grow, despite annexation and consolidation by urban communities, and the wide disparity that once existed…

The imprecision of some concepts used in formal models in information science has led to attempts to apply fuzzy set theory to aspects of information science. An analysis of various kinds of imprecision that can occur indicates that fuzzy set theory is not an appropriate formalism for these models. (Author/MBR)

This informal survey found that the probability that a person is in the over 45 age group, and is left-handed, is significantly different from the probability in the population as a whole. (MP)

The effect of general and specific cues on learning information from graphs is analyzed. The study shows that the use of cues influenced the amount of information learned, with variations according to type and placement of cues. (JMF)

Discussed are programs for the TRS-80 to draw vertical and horizontal bar graphs. A short set of exercises is included. (MP)

The calculator is used to obtain values for use in graphing curves. Three worksheets are included. (MP)

Practical decisions involving fuel economy are shown to require important skills from secondary school algebra and analysis. (MP)

A quantitative comparison of peer versus bibliometric procedures for rating the quality of U.S. universities is presented. The quality of graduate faculty is measured by the Roose-Andersen peer rating, while bibliometric ratings are based on the number, average "quality," and total influence of university papers in each field.…

In a study involving the reading of bar graphs it was found that students in the control group (who did not receive generalization cues) did significantly better than those in the experimental group. (Ed.)

Two graphing activities are supplied for providing practice in plotting points in the rectangular coordinate system. (JT)

Four activities providing experience in building bar graphs, reading and building circle graphs, and graphing in a coordinate plane are described. (JT)

A system similar to the slope method of graphing a linear equation is described for graphing parabolas. (JT)

This article provides a discussion of issues related to the standardization of technical illustrations using graph paper based on multiples of 100 mm. (SD)

In the process of fitting a quantitative synthesis model, the assumption of homogeneous effect size variation is assessed via omnibus test statistics. Graphical representations of data on techniques for teaching composition skills are used to help determine the extent to which sample estimates deviate from modeled population estimates. (TJH)
