Box-Whisker Diagrams 50% Probability Density Graph (“Bell Curve”) Median – Middle Value Min/Max Value Box Whiskers What are they? Min/Max Value 25%

Box-Whisker Diagrams What Can We Use Them For? ABCD 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.
