The purposes of this study were to demonstrate a methodology for local development of slide-tape occupational information materials, and to determine whether this was a more effective means of conveying this information than printed or aural presentations. The results indicate the slide-tape mode was the most effective. (Author)

Advantages of the use of multivariate commonality analysis are discussed and a small data set is used to illustrate the analysis and as a model to enable readers to conduct such an analysis. A noteworthy advantage of commonality analysis is that commonality honors the relationships among variables by determining the degree to which predictors in a…
