Interpreting a Box-Whisker Chart

Each Box-Whisker represents the specified Characteristics' process location (the centerline) and variation (box boundaries, and whiskers). The calculations of the centerline, box boundaries and whisker boundaries are dependant on user-specified options. As an enumerative statistical tool, care should be taken in its interpretation. Unless statistical control of the underlying process is established, the statistics presented on the Box-Whisker may not be reflective of the expected process outcome.
