De grafiek is correct maar de bijhorende interpretatie is fout.
Aan de hand van de notched boxplots kunnen we zien dat de laatste investering (UT90) op het eerste zicht het best lijkt. Deze investering biedt een return die significant hoger ligt dan 3.8%, nl 4.84%. Vergeleken met de eerste drie is de kans zeer klein dat de hogere mediaan aan het toeval is toegeschreven. In vergelijking met de voorlaatste investering (UT70) is de kans op toeval echter groter. Ook deze voorlaatste investering biedt een return die significant hoger is dan 3.8%, nl 4.37%. We kunnen dus stellen dat deze hogere mediaan niet significant is.
De rode lijn is dus niet noodzakelijk. Deze is alleen nodig om een beter beeld te schetsen van de investeringen die voldoen aan het minimum vooropgestelde percentage nl 3,8%.

geen conclusie vermeld.
mijn conclusie: De notched boxplots tonen os de hoogste mediaan bij de laatste investeringsopportuniteit. Deze is enkel significant verschillend t.o.v. de eerste en de tweede box plot, waaruit we kunnen besluiten dat dit niet door toeval wordt veroorzaakt.

Je moet altijd de betrouwbaarheid controleren,bij deze notched boxplot zijn de gegevens niet betrouwbaar daar de inkepingen elkaar overlappen.3.8%is het beste en al wat er boven ligt is goed vb. UT90
