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.
We kunnen van een histogram ook niet afleiden of een datareeks daalt of stijgt. Dit gaat niet omdat men bij een histogram de data's rangschikt van klein naar groot.
