Q1:

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.
