Software for advanced ANOVA courses: A survey

In response to a survey of faculty regarding their commercial software preferences for advanced analysis of variance courses, it was found that the most frequently used packages were SAS, SPSS^x, and BMDP, all originally mainframe packages. The fourth choice, SYSTAT, was written for microcomputers but is currently also available for other host computers. Difficulty for students was the most frequently cited reason fornot using one of these four packages. The most important criteria for choosing software packages were variety of designs, accuracy, and ease of use. Cost was a factor only for microcomputer licenses. Packages using the general linear model approach were paramount to some, while others would not consider such packages. Instructors decried the lack of the “ideal program,” but the diversity of their desires makes it clear that no program could be ideal for all of them. Many faculty seemed unaware of newer software packages or of the extent to which older packages (particularly Minitab) have been modified; some had their choices constrained by departmental limitations. Better dissemination of information about statistical software is needed, whether it be from software publishers or through the professional literature.
