Ook hier weer dezelfde opmerking als bij de eerste en tweede berekening. Hier is er een hoge positieve correlatie. Punten met eenzelfde density worden met elkaar veronden zodat er hoogtelijnen ontstaan. De meeste punten en cluster liggen redelijk dicht bij de rechte. Een rode kleur betekent dat er een hoge density is.
