Je kan vaststellen dat het gemiddelde van de kledingproductie, beduidend lager ligt dan het gemiddelde van de totale productie.
Aan de hand van deze grafiek kan je echter niet zien of er sprake is van een stijgende of dalende productie, zoals de student ook al aanhaalde.

Op de back-to-back histogram kan je duidelijk aflezen dat de 2 grafieken van elkaar verschillen, het gaat hier dan ook over onafhankelijke datasets.
Toch is het belangrijk om te weten dat we geen significant verschil kunnen aantonen, dit moet namelijk statistisch verantwoord kunnen worden en we kunnen dit niet wetenschappelijk bewijzen.
Zoals reeds vermeldt door mijn collega's kunnen we van een histogram niet afleiden of een datareeks daalt of stijgt. Dit gaat niet omdat men bij een histogram de data's rangschikt van klein naar groot. Zoals reeds vermeldt door mijn collega's
