Wat is handiger om te vermelden wat de variabele z is, voor de duidelijkheid. Er is inderdaad een sterke correlatie tussen X en Y, tevens heeft z heeft hier weinig invloed op.

over welke variabelen gaat het hier? goede grafiek en juiste conclusies getrokken
  2008-11-21 23:05:22 [Vincent Vanden Poel] [reply] 
X = Totale industrie
Y = Vervaardiging van transportmiddelen
Z = Afzetprijsindexen - binnenlandse markt : Vervaardiging en assemblage van auto's, aanhangwagens en opleggers

Juiste weergave en conclusie. De partiële correlatie werkt inderdaad het storende effect van de 3de variabele weg waardoor de schijncorrelatie verdwijnt.
