De student heeft de juiste methode gebruikt maar hij heeft te weinig observaties ingevoerd. Er moeten er minsten 60 zijn. De student heeft zijn berekening ook niet verder gemotiveerd.

De student heeft zijn/haar tijdreeksen niet in het document geplaatst. Hierdoor weet ik niet welke datasets hij/zij hier vergelijkt. Ook zegt de student dit niet in zijn/haar document. Er zijn geen conclusies getrokken. De student zal aan de hand van de oplossingen die in de les zijn gegeven, de oefening opnieuw moeten maken.

Ook zijn de tijdreeksen die de student gebruikt niet correct. Een tijdreeks moet minstens 60 maandelijkse observaties bevatten. Hij of zij gebruikt veel te weinig observaties.

Q2:

De student heeft geen poging gedaan om een oplossing te formuleren. De vraag is onbeantwoord gebleven.
