Evaluatie opdracht 2: Task 3: 
De student is er niet in geslaagd om een horizontale lijn op de grafiek te zetten, waardoor het duidelijker zichtbaar is welke investering de beste is. Deze lijn kan eenvoudig getekend worden door pen en lat. Zoals de student vermeldde eist de financieel adviseur een minimum rendement van 3,8%: dit betekent dat als een investering hieraan wilt voldoen, het betrouwbaarheidsinterval (is het interval waartussen de mediaan kan fluctueren) boven de waarde 103,8 moet liggen. De student was van mening dat enkel de mediaan boven deze minimumlijn moet liggen, maar dit is niet waar: het is belangrijk dat ook het betrouwbaarheidsinterval daarboven ligt, want als de mediaan toevallig gelijk zal vallen met de lower bound van het interval, dan kan deze mediaan onder de horizontale lijn liggen (als het betrouwbaarheidsinterval niet volledig boven deze minimumlijn ligt). Bij de laatste zijn de inkepingen zeker hoger dan de horizontale lijn; bij de voorlaatste investering is er twijfel: de lower bound van het betrouwbaarheidsinterval ligt ongeveer op de horizontale lijn. Om er nu zeker van te zijn of deze boven de minimumlijn ligt, moeten we gaan kijken naar de tabel met de gegevens van de lower en upper bound van de mediaan. Daaruit blijkt dat de ondergrens van het betrouwbaarheidsinterval nog net boven de horizontale lijn ligt, maar het is duidelijk dat zowel de mediaan als het betrouwbaarheidsinterval de laatste investering een stuk hoger ligt dan het minimumrendement en deze investering is dan ook het meest interessant voor de financieel adviseur.

Het antwoord is correct al zou ik graag nog het volgende willen opmerken : Zoals de studente reeds zelf al heeft beschreven in haar evaluatie,was zij vergeten rekening te houden met de ondergrens van de mediaan. Bij de eerste drie investeringen (IND90_UT10, IND70_UT30 en IND50_UT50) kan de mediaan tot onder de grens van 103,8 schommelen. Dit wil dus zeggen dat minstens 50% van de gegevens onder deze grens zouden terecht komen.Hierooor kwamen deze boxplots dus al zeker niet aanmerking als beste investering. Graag zou ik ook eventjes de ondergrens ter sprake willen brengen. 75% van de gegevens ligt boven deze grens dus al deze grens boven 103,8 ligt (zoals bij de twee laatste investeringen) wil dit zeggen dat 75% van de gegevens in aanmerking komt voor het gewenste return on investment.
