De student heeft kort zijn interpretatie van het back-to-back histogram weergegeven. Hij had nog een iets uitgebreidere analyse van het histogram kunnen geven.
Zo kan er afgeleidt worden dat de mediaan bij de totale productie meer links ligt en hoger en bij kledij meer naar onder omdat de kledingproductie afgezwakt is.
De spreiding is ongeveer even groot (hoe meer er aan de kanten observaties zijn hoe groter de spreiding).
We kunnen ook vaststellen dat het gemiddelde van kledij visueel verschilt van de totale productie, om aan te tonen dat het significant verschilt hebben we meer tests nodig.

Ik had hier inderdaad meer uitleg kunnen geven over de grafieken.

Een korte maar correcte interpretatie, hij had inderdaad een meer uitgebreide analyse van het histogram kunnen weergeven.
Vb.: de mediaan bij de totale productie = links + hoger (kledij = afgezwakt)
