Hi :) What is the difference between "Large cumulative deviation over part of the age range" and "Excessive clumping of deviations of the same sign"? 

A diagram would also be useful. Thanks

Attached is an image where I try explain the difference. The first one is difficult to see diagrammatically, but has a nice mathematical interpretation. The second has a good diagrammatical interpretation.

Hope this helps!
