SAS software offers guided (prompt-driven) data analysis for engineering and research applications. Analysts are led through basic methods of statistical analysis (such as analysis of variance and covariance, univariate analysis, one-way ANOVA, and linear and multiple regression) that can be represented graphically with scatter plots, histograms, box-and-whisker plots, and contour plots. An online journal facility stores text and graphical output, software-generated analysis interpretation, and personal comments.
