'unverified author' en 60 blockwiths ipv 12.

weeral de blockwidth, daardoor kunnen er niet zo veel conclusies getrokken worden!

De oefening het aanpassen van de R-code is correct uitgevoerd.

Toch gelden hier dezelfde opmerkingen als in Q2 en Q3 over de witdh en foutief bloggen.

Het is juist dat ik de breedte van de blocks ongemoeid had moeten laten. Nu ik ze veranderd heb naar een blockwidth is het niet mogelijk om voldoende conclusies te trekken.

de R code is goed aangepast maar de blockwith moet op 12 blijven staan. Als algemene conclusie kan je stellen dat de spreiding van de gegevens kleiner zal worden.
