Idem opmerking bij berekening 1, 2 en 3. Hier is er een hoge positieve correltie van 0.97. Op de grafiek zijn er 3 clusters waar te nemen rond de stijgende rechte. Punten met eenzelfde density worden met elkaar voerbonden zodat er hoogtelijnen ontstaan. Een rode kleur duidt aan dat er een hoge density is.
