Wat zijn je conclusies?

Er werden geen conclusies getrokken.

Je zou kunnen zeggen dat er in de 11de maand duidelijk spraken is van seizoenaliteit. De mediaan schommelt over de jaren heen niet zo sterk, hij daalt eerst, maar stijgt later weer.

Eigen verbetering:
In maand 11 is er duidelijk een teken van seizoenaliteit doordat de grafiek hier opeens zeer hard daalt. De observaties blijven voor maand 11 relatief dicht bij de mean, dit betekent dat de gegevens relatief weinig fluctueren.
