We dienen bij de interpretatie van de software uit te gaan van volgende nulhypothese: er bestaat geen verband tussen beiden. We zien inderdaad een kleine P waarde. Dit betekent dat we de nulhypothese zullen verwerpen en dus zullen aannemen dat er wel degelijk een verband bestaat tussen Separate en Happiness.

Vervolgens kijken we naar de grafische voorstelling 'associatie plot'; deze leert ons dat er een positief (maar niet noodzakelijk een causaal) verband bestaat tussen beiden.
