Evaluatie opdracht 1: Task 2: 
De grafiek is op een juiste manier gemaakt. Ook de conclusie vind ik zeer goed beschreven: de lower en upper bound van de mediaan van variabele 4 liggen een heel stuk onder de lower en upper bounds van de medianen van de andere variabelen. Aangezien de betrouwbaarheidsintervallen van variabele 4 de andere inkepingen niet overlappen, is er hier sprake van een slechte evolutie van deze variabele. Bij deze oefening zegt de variantie van de variabele niets over het feit of er al dan niet sprake is van een slechte evolutie. 
De student heeft er evenens bij vermeld dat de mediaan van de vierde variabele een heel stuk onder het basisjaar lag en dat er rekening moet gehouden worden met de outliers, want dat deze mogelijk een vertekend beeld kunnen geven: daar ben ik het ook volledig met eens.
