Bij de Partial correlation is ook een algemene interpretatie nodig.Partiële correlatie meet de correlatie tussen 2 variabelen met het wegnemen van het effect van een andere variabele op deze correlatie. Zo kan men echt goed de pure correlatie tussen 2 variabelen meten door de eliminatie van een storende variabele.Bv ooievaarsnesten en baby’s sterke correlatie, dit is omdat er een derde variabele z bestaat, die deze correlatie veroorzaakt. Berekent de correlatie, na de wegwerking van de z-variabele. (bij baby en ooievaar kleine partiele corr)
