A table of critical values is presented for use with Chacko's ordered alternatives test for the analysis of variance. (Author/JKS)

Discussion of the use of computer-based information retrieval systems in schools focuses on three paper and pencil experiments conducted in the United Kingdom that were designed to investigate how 9- to 11-year-olds organized and retrieved information from four organizational structures: lists, hierarchies, networks, and tables. (18 references)…

Describes study of college students that was conducted to determine whether increasing the amount of data in different graphic formats affects the interpretation of quantitative information. Immediate and delayed recall are examined, and correlations between graphic format and field dependence and independence are discussed. (12 references) (LRW)

Points out that 108 studies in the first 25 volumes of AV Communication Review used univariate analysis of variance to test experimental hypotheses, and suggests that researchers include omega-squared values in their reports to permit estimation of the relationship between x and y variables, and correlation data for comparing studies.

Describes a computer program called AnoGen that automates the process of generating data sets for ANOVA designs and operates within DOS and Windows compatible computers. Explains that the program runs in both student and teacher modes and is freely available for noncommercial use through the Internet. (CMK)

The paper obtains a maximum likelihood criterion test for multisample sphericity. The test contains Mauchly's sphericity test as a special case. (Author)

A computer program written in BASIC is described which performs one-way analysis of variance based on the mean, standard deviation, and size of each group. Output lists a full analysis of variance table. (Author)

The various costs of Type I and Type II errors of inference from data are discussed. Six methods for minimizing each error type are presented, which may be employed even after data collection for Type I and which minimizes Type II errors by a study design and analytical means combination. (Author/CM)

A general analysis strategy is proposed such that the universe of inference is increased incrementally. The strategy prevents logically incongruent findings that occasionally result when the conventional analysis strategy is employed. (Author)

Multiple comparisons involve the examination of which group or groups are actually different from other group(s) in analysis of variance results. Such comparisons usually involve one-way analysis of variance. This monograph discusses designs more complex than one-way designs. (JKS)

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)

Discussion of interactive classroom technology systems highlights experiments with a new interactive system called RESPONDEX which was used for both course delivery and diagnostic data collection. Studies included class break duration; truthfulness in response to sensitive questions; course design monitoring; and personality and learning style…

Logically consistent hypothesis-testing for factorial analysis of variance designs is proposed in the context of a hierarchical model. It is shown that all of the hypotheses associated with the traditional factorial model are conceptually independent and occupy the lowest levels of the hierarchy. (Author/JKS)

The equivalence of one-way multivariate analysis of variance and canonical correlation is well known. The usefulness of canonical correlation analysis is performing factorial multivariate analysis of variance is demonstrated. (Author)

The effect of the variance stabilizing transformations on the significance level and power of the F test, applied to Binomial and Poisson variables, was examined by a Monte Carlo study. The results indicate that the significance level is not affected by the transformations. (Author/JKS)
