Use the Analysis of Means Chart to analyze the differences in means
The Analysis of Means Chart is like a control chart with a center line and upper and lower decision limits. Means outside of the decision limits are considered to be statistically different from the overall mean (i.e., average).
In the Analysis of Means Chart above, we are comparing seven operators. Since operators 6 and 7 have means outside of the UDL and LDL respectively, they would be considered statistically different from the overall mean.
The Analysis of Means Chart is one of many charts that can be created right in Excel using QI Macros add-in.
