Box-Whisker DiagramsWhat Can We Use Them For?

A B C D

A – A “Good” System. Box and whiskers are short and compact.

B – A “Bad” System. Results are all over the place. Box and whiskers are stretched out.

C – A “Consistently Bad” System. Compact but well above TN limit (19 mg/l)

D – A “Usually Pretty Good” System. Compact but maybe a couple of high results.
