De conclusie is correct al kunnen we er hier nog aan toe voegen dat x een zeer grote invloed heeft op de correlatie tussen variabelen y en z.

Bij de partiële correlatie worden de gegevens van de derde variabele eerst weggewerkt. Je kan zien in hoeverre een variabele een positief of negatief effect heeft op een variabele. In de laatste twee tabellen kan je zien dat de X een groot effect heeft op de variabelen Y en Z. In de laatste tabel kan je dit heel goed zien omdat de correlatie daar negatief is geworden.

Correcte conclusie maar zelfde op merking als Gert-Jan Geudens
