Ze heeft de juiste techniek gebruikt en is tot de juiste conclusie gekomen. Een extra detail dat ze er had kunnen bijzetten was dat de mediaan van de kledingproductie significant lager ligt dan deze van de totale productie, dus dat dit niet te wijten is aan toevalligheid. Dit kan men afleiden door de uiteinden van de notches van de kledingproductie door te trekken tot aan de grafiek van de totale productie. Deze lijnen komen niet in de buurt van de uiteinden van de nothces van de totale productie en daaruit kan je dan besluiten dat het verschil significant is.

We kunnen uit de box plots heel duidelijk zien dat de mediaan van de kledij beduidend lager ligt dan de mediaan van de totale productie

De student heeft de juiste techniek toegepast en is tot de juiste conclusie gekomen. Een beter antwoord had wel kunnen zijn: de mediaan van de totale productie ligt significant hoger dan de mediaan van de kledingproductie. Dit kunnen we afleiden aan de hand van de betrouwbaarheidsintervallen, deze liggen voldoende van elkaar verwijderd.
