Negotiations proposals can be evaluated by assigning advantage points and plotting these values on a negotiations analysis graph. Provided to illustrate the procedure are a table containing all proposal items submitted by both bargaining teams showing advantage point evaluations; four figures, each with four graphs, are also included. (MLF)

Canonical analysis of two convex polyhedral cones involves looking for two vectors whose square cosine is a maximum. New results about the properties of the optimal solution to this problem are presented. The convergence of an alternating least squares algorithm and properties of limits of calculated sequences are discussed. (SLD)

Simple experiences with probability can extend third graders' understanding of the need for fractions. Three activities are given which build on language-arts experiences and incorporate concepts in multiplication, graphs, and fractions. (MNS)

The form of item log-likelihood surface was investigated under two-parameter and three-parameter logistic models. Results confirm that the LOGIST program procedures used to locate the maximum of the likelihood functions are consistent with the form of the item log-likelihood surface. (SLD)

Reviews studies in which perceptual cue trading data have been compared with computational models and examines the perception of contrast between the voiceless fricative "s" and the voiceless affricate "ts." Nine subjects listened to a total of 6 tokens each of 193 stimuli and labeled each stimulus as containing either of the…

Describes data analysis activities for grades three through six using unshelled peanuts. Includes two reproducible student worksheets. (MKR)

Describes exploratory data analysis activities using packages of M&M candies and graphing results using object graphs, picture graphs, symbolic graphs, circle graphs, relative-frequency bar graphs, and stacked bar graphs. Also discusses pooling data and assessing reasonableness of results. (MKR)

Quick power estimates for detecting a difference in two population proportions are expedient during early stages of research planning. Such estimates are tabled and graphed in this article. They are shown to be conservative but accurate for most research situations when proportions fall in the range of 0.25 to 0.75. (SLD)

It is argued that there is a benefit to applying techniques of exploratory data analysis (EDA) to program evaluation. The evaluation of a rehabilitation program for people with rheumatoid arthritis (20 subjects and 21 comparisons) through EDA supports the argument, indicating outcomes more precisely than conventional analysis of variance. (SLD)

Examines materials about laserdisks in literature published between 1970 and 1989 that addresses library applications. Searches on ERIC, Information Science Abstracts, Library and Information Science Abstracts, and Library Literature are reviewed; core laserdisk journals are discussed; indexing overlap is examined; and other online databases are…

A technique is presented to transform incomplete categorical data into complete data by imputing appropriate scores into missing cells. A solution of the optimization problem is suggested, and relevant psychometric theory is discussed. The average correlation should be at least 0.50 before the method becomes practical. (SLD)

Discussed is the difficulty that students encounter when attempting to distinguish between independent and dependent variables, not only in the mathematics classroom, but also when devising and labeling graphs resulting from chemistry or physics experiments. (JJK)

Analysis of the effect of providing a graphic representation of knowledge structures to seventh grade students of English as a Second Language found that the teaching strategy, to which students reacted favorably, facilitated comprehension and immediate recall. (42 references) (Author/CB)

Presents a rationale for including applied functions and graphs in developmental mathematics courses, arguing that the ability to construct, interpret, and represent functional relationships is important in every discipline. Discusses student difficulties with abstract and applied functions and curricular and instructional implications. (DMM)
