Statistics used to estimate the population correlation ratio were reviewed and evaluated. The sampling distributions of Kelly's and Hays' statistics were studied empirically by computer simulation within the context of a three level one-way fixed effects analysis of variance design. (Author/RC)

The author illustrates the shortcomings of pooling data from replication and original studies. If combining data is deemed necessary, procedures should be rigorous to identify statistically widen study differences. When sources of variation are easily identifiable, an analysis of variance may be superior to a series of separate t-tests.…

Examined and measured effects of individual differences among the elderly in a cognitive training program emphasizing general learning skills. Memory improvement was greater for learning skill training and social support compared with a waiting list group. Individual variability obscured statistical differences in treatment effect. Examined…

Application of the Kruskal-Wallis test to survey research problems is discussed as an alternative for the business education researcher in testing questionnaire response differences among three or more independent groups. Problem illustrations and a computer program are included. (MF)

The purpose of this study was to determise the relative loss in statistical power of traditional methods of analysis when response-shift bias is present. Five methods of analysis (posttest scores only; postminus pretests; postminus retrospective pretest; postcovaried by pretest; postcovaried by retrospective pretest) were compared. (Author/BW)

Hypothetical data sets are used to demonstrate how canonical correlation methods subsume other commonly utilized parametric methods. Analysis of variance, analysis of covariance, multiple analysis of variance, and multiple analysis of covariance are heavily used by educational researchers. It is concluded that researchers would do well to consider…

Describes a study that was conducted to assess the educational value of simulation gaming in business policy courses. Student and practitioner perceptions of simulation effectiveness are examined and compared; relevant literature is reviewed and research problems are discussed; and the importance of various managerial skills is considered. (30…

The utility of the biomedical model of adjusted statistics is demonstrated. The model is recommended for use by educational researchers to randomize subjects for a more accurate estimate of school programs' success or failure when compared across classrooms or other units. (Author/MH)

When two groups, initially dissimilar, undergo different treatments, can subsequent differences be partitioned in such a way that the difference between the two treatments is unbiased? This is the central problem of this paper, and it is confronted by the examination of two levels of information using a Follow Through Evaluation. The first…
