Juiste uitvoering en juiste uitleg.

deze opdracht is correct uitgevoerd. De reproductie was eigenlijk niet nodig aangezien de gegevens altijd dezelfde blijven en dus steeds hetzelfde resultaat bekomen wordt, mr het is dus niet foutief.

Een reproductie was inderdaad overbodig volgens mij. De student heeft het wel goed gedaan; zowel de interpretatie van de cijfers als de uitleg van de 'werkwijze'.
