Ook deze berekening is niet juist. 
 
Deze wel: http://www.freestatistics.org/blog/date/2008/Nov/07/t1226071764tqfspk7trjlwma1.htm 
 
Logaritmen worden gebruikt om grote getallen kleiner te maken, terwijl de kleine getallen relatief gezien minder klein worden. Met andere woorden: grote schommelingen worden afgezwakt, terwijl kleine schommelingen worden versterkt. 
 
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.

Ook hier zet Stijn zijn fout goed recht. Hij maakt hier de correcte reproductie. 
Voor de rest is zijn uitleg zeer duidelijk en correct.
