Niet volledig (1/2).
De student heeft de aantal bins (interval) veranderd naar 20, terwijl 30 een betere optie zou zijn. Er zijn ook nog andere mogelijkheden om het interval aan te passen. Bijvoorbeeld door een lijn in de R code toe te voegen (= x <- x[x<700])

De bedoeling bij het bloggen van een goed histogram was goed. De student heeft het aantal klassen veranderd naar 40. De bedoeling was goed, maar ik vind dat de grafiek toch nog geen overzichtelijk beeld weergeeft van de gegevens. We kunnen hem dus nog beter verfijnen. Indien de student het aantal klassen had gewijzigd naar 14, dan had de student een nog beter beeld bekomen van de gegevens. Hierdoor zouden we een meer normale verdeling krijgen en worden de gegevens meer gespreid.
een voorbeeld hiervan vind je op onderstaande link :

Uit het histogram lijkt 250 seconden een goede schatting voor het invullen van een enquête.
Een andere oplossing is de extreme waarden verwijderen (handmatig of aanpassen software)

De student maakt een juiste verwerking door het aantal bins te wijzigen. Hij zou ter verduidelijking van de grafiek eventueel de uitschieters kunnen verwijderen (handmatig, of door wijziging van de R-Code).
De suggestie van een medestudent(e) hierboven- om het aantal bins te herleiden tot 14 vind ik ook een goed alternatief.
