The patterns on this tab should be watched in addition to the patterns of instability. The ability to recognize these patterns can greatly increase the usefulness of the control chart by permitting a fuller interpretation of its meaning. These patterns are different from the patterns of instability in that both halves of the control chart are considered together in looking for the patterns.
