Box-Whisker Diagrams What 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. A B C D
