Correct. 
 
De bedoeling is dus om de spreiding te verkleinen en de betrouwbaarheid te verhogen. 
 
We zien dat de ‘lower bound’ en ‘upper bound’ nu dichter bij de ‘median’ liggen. 
 
Op te merken valt dat je met deze methode geen gebruik kan maken van negatieve getallen.

Deze bewerking werkt correct uitgevoerd. Wat doet een logaritme nu eigenlijk? een logaritme zorgt ervoor dat grote getallen veel kleiner worden. Grote schommelingen in de dataset worden afgezwakt. De spreiding zal dus ook verkleinen.

Ook hier een correcte uitleg waarom de logaritmes worden gebruikt. Voorts een correcte uitvoering. 
 
We passen de R-code aan en we zien dat de seasonaliteit d.m.v. logaritmen een beetje ingedrukt wordt. Je gaat de spreiding verkleinen. We zien op de grafiek bij de investeringen de twee uiterste outliers niet meer.  
Er mogen geen negatieve getallen zijn bij logaritmen.
