SPC for Excel contains three major methods of determining if there are significant differences in the treatment (process) means. These include Fisher's LSD method, Tukey's method, and Bonferroni's method. Equality of variances is tested using Bartlett's method or Levene's method. In each method, the software clearly tells you if significant differences are found and which treatment means or variances are different. The software also contains the Analysis of Means method to determine if there are significant differences in treatment means. Box and Whisker plots give a visual picture of the median locations and the spread in the data.
