The Analysis of Variance(ANOVA) is a general tool for analysing desinged experiments. Among the many statistical softwares on ANOVA available in personal computers, we will review SAS(version 6.04), SPSS/PC+(version 4.0) and S-PLUS(version 2.0). SAS and SPSS/PC+are popular data analysis systems, and S-PLUS is an interactive graphical data analysis system. Statistical graphics give many informations aobut the main effects and the interaction effects in experimental data, and diagnostics about the model design. S-PLUS is very useful in these respects. Combining the analysis by SAS ans SPSS/PC+ with graphical displays of S-PLUS will give good interpretation of designed experiments.
