Je zegt in je oplossing dat dit Back-2-backhistogram redelijk gelijk loopt op enkele uitzonderingen na.

Ik interpreteer dit back-to-back histogram toch een beetje anders. Zo zie je wanneer 1 kant toeneemt, de andere kant niet volgt. De 2 histogrammen spiegelen ook niet in geen enkel opzicht en wanneer het aan 1 kant verminderd kan het aan de andere kant verdriedubbelen.

Wat je wel kan waarnemen is dat de algemene index eerder links-skewed is en de gezondheidsindex rechts-skewed. Maar deze termen kende je nog niet tijdens het maken van de oefening.
