Deze vraag werd verkeerd beantwoord door de student, hij heeft het juiste back-to-back histogram maar heeft de verkeerde conclusie getrokken.
De distributie of spreiding verloopt wel degelijk gelijkaardig. Wanneer je het aantal blokjes telt, tel je aan de ene zijde 8 en aan de andere zijde 9, dus verloopt de spreidng gelijkaardig.
Van het back-to-back histogram kunnen we eveneens de mediaan en het gemiddelde bekijken, waar die ongeveer ligt. Deze van de kleren ligt lager dan die van de totale productie. Dit omdat de datareeks van de kleren daalt en die van de totale productie stijgt. Dit kunnen we echter niet aflezen, want bij het back-to-back histogram ga je ordenen en een datareeks is chronologisch.

De student heeft de vraag correct beantwoord. Er kan wel aan toe gevoegd worden dat er een ongeveer gelijkaardige spreiding te zien is op beide grafieken.
