Each Analysis of Means Methods option adds a chart to the report window that shows the following:

• an upper decision limit (UDL)

• a lower decision limit (LDL)

• a horizontal (center) line that falls between the decision limits and is positioned as follows:

– ANOM: the overall mean

– ANOM with Transformed Ranks: the overall mean of the transformed ranks

– ANOM for Variances: the root mean square error (or MSE when in variance scale)

– ANOM for Variances with Levene (ADM): the overall absolute deviation from the mean

– ANOM for Ranges: the mean of the group ranges

If a group’s plotted statistic falls outside of the decision limits, then the test indicates that there is a statistical difference between that group’s statistic and the overall average of the statistic for all the groups.
