De student maakt de berekeningen maar geeft geen uitleg.

De partial correlation berekent de verschillende correlaties onderling tussen de gegevens.

Partial Correlation: hier maakt men berekeningen aan de hand van 3 variabelen. Alle correlaties worden berekend, maar voor de partiële correlatie wordt de 3de variabele gezuiverd. De 3de variabele kan een vertekend beeld geven.

De student heeft wel de goede berekeningen gemaakt, maar 'vergeet' ze te interpreteren. De partiële correlatie laat de onderlinge correlatie zien nadat sommige waarden zijn weggewerkt. Het risico is wel dat er altijd een verkeerd beeld kan gegeven worden.
