De verwerking van metaal stijgt inderdaad gedurende deze 5 jaar. Je kan ook nog zien dat er in maand 6 en 7 spraken is van seizoenaliteit.

Hier zien we duidelijke pieken en dalingen in de meanplot. Maar nu weten we nog niet of het om een significant verschil gaat. Daarvoor moeten we kijken naar de box plot periodic subseries daarin zien we dat de betrouwbaarheidsintervallen bij 6 en 7 en bij 8 en 9 heel ver uit elkaar liggen. Dit wijst op een significant verschil.

We kunnen inderdaad bij de sequentional blocks zien dat er een algemene stijging is, maar deze is niet significant aangezien de betrouwbaarheidsintervallen nog in elkaars velden liggen. Bij de Box Plot periodic zien we inderdaad dat er verschillen zijn in de maanden waardoor we kunnen spreken significatie tussen bijvoorbeeld de maanden 6 en 7 en 8 en 9.
