Evaluatie opdracht 1: Task 2:
Ik ben van mening dat niet alles relevant is wat in de conclusie staat. De spreiding/variantie van de Notched Boxplot zegt niets over de relatief grootste daling sinds maart 2001. Het is inderdaad zo dat de mediaan van de vierde variabele veel lager ligt dan de mediaan van de andere variabelen. Dit betekent echter niet dat dit verschil in ligging significant is. In dit geval overlapt het betrouwbaarheidsinterval van de laatste variabele de inkepingen van de Notched Boxplots van de andere variabelen niet: er is dus sprake van een significant verschil en dus niet van toeval. De investeringen zijn dus inderdaad het sterkst gedaald ten opzichte van het basisjaar. Dit wordt ook bevestigd door de tabel met daarin de gegevens van de lower en upper bound van de mediaan: dit interval ligt ook duidelijk lager dan de andere intervallen van de medianen. Dit interval overlapt ook geen enkel ander interval, dus het verschil is significant. We kunnen dus stellen dat de hypothesis klopt. We moeten echter wel rekening houden met de outliers van de vierde variabele: deze kunnen mogelijk een vertekend beeld geven.

De investeringen zijn inderdaad het hardste gedaald van alle variabelen. Doordat de notches elkaar niet overlappen is ook hier de daling niet te wijten aan toeval. De investeringen zijn nu 45,5% lager dan in het basisjaar 2000
