Provides an expository presentation of multivariate analysis (MANOVA). Addresses several questions relating to why one should use MANOVA, its structure, how MANOVA test statistics and follow-up tests are obtained and interpreted, presentation of results, and alternatives to MANOVA. Uses an example data set to illustrate these points. (Author/KS)

Reviews a computer-assisted learning package (available from CONDUIT) which introduces survey and sampling techniques by pretending that the user is a pollster asking one of six questions of a more or less political nature. Documentation and performance are rated fair while ease of use is considered excellent. (JN)

Some sample data used in economic education research may be biased because missing observations may not be random. The authors explain a technique for estimating the relationship between students who fail to take standardized tests (the missing observations) and a core of general variables that might explain this behavior.

Several samples of black and white students were drawn from the 1970 PSAT administration in Georgia and studies for item x race interaction on both the verbal and mathematical sections of the test. (Authors)

When evaluating the effectiveness of an educational program, multiple matrix sampling is particularly effective and efficient when the goal of the evaluation is estimating group (as opposed to individual) performance. The technique is described in some detail, with its advantages and disadvantages, and examples of its application are given.…

Questions are raised concerning differences between traditional metric multiple regression, which assumes all variables to be measured on interval scales, and nonmetric multiple regression. The ordinal model is generally superior in fitting derivation samples but the metric technique fits better than the nonmetric in cross-validation samples.…

Discusses the importance of a knowledge of basic statistical concepts for a librarian's education, and the problem of implementing such an introductory course. Two class exercises dealing with sampling and probability and the Central Limit Theorem are described, and 11 references are included. (BK)

Dunnett's procedure for comparing K-1 treatments with a control is discussed within the context of three nonparametric models: those of Kruskal-Wallis, Friedman, and Cochran. (Author/MH)

Equating two parallel forms of the College Board Biology Achievement Test using three sampling strategies was examined. For each strategy, five equating procedures were studied: Tucker and Levine equally reliable linear equatings; frequency estimation equipercentile equatings; chained equipercentile curvilinear equatings; and three-parameter…

Discusses how to use attribute sampling to assess the accuracy of a library circulation system. Describes the nature of sampling, sampling risk, and nonsampling error. Presents nine steps for using attribute sampling to determine the maximum percentage of incorrect records in a circulation system. (AEF)

Introduces some of the considerations behind the teaching of research methodology at the Royal School of Library and Information Science (Denmark) at the masters level. Discusses information retrieval experiments; sampling problems; the concept of a model; and statistical analysis and its role in information retrieval experiments. (Contains 25…

Describes a hands-on demonstration of the concept of the sampling distribution of the mean using M&M's candy. Compares the effectiveness of the candy demonstration with that of a comparable demonstration using a textbook example. Reports that students exposed to the candy example performed better on a subsequent examination. (DSK)
