De berekeningen met de software gebeurden ook hier op een correcte manier en met de correcte gegevens. Echter zou het nog beter geweest zijn wanneer men de notched boxplots van de mannen en deze van de vrouwen op één voorstelling zou plaatsen. Een voorbeeld daarvan vindt men hier: http://www.freestatistics.org/blog/date/2010/Oct/15/t1287141811ph614ld5bgz5kmv.htm/ 
 
De conclusies die werden getrokken zijn correct en zijn voornamelijk gebaseerd op die boxplots waarvan de 'notches' niet overlappen.  
 
Men zou daarnaast ook nog iets kunnen opmerken over waar de notches wel overlappen, deze observaties zijn dan namelijk (min of meer) vergelijkbaar met elkaar. Dit ziet men voor het derde type van intrinsieke motivatie alsook voor het eerste, tweede en derde type van extrinsieke motivatie.

Je hebt de boxplots goed gemaakt, het was iets beter geweest moest je de gegevens van zowel de mannen als de vrouwen in 1 notched boxplot geplaatst hebben.

De bovenstaande link toont alles in 1 figuur. 
 
Je ziet dat de meeste boxplots elkaar overlappen, over het algemeen zijn de vrouwen iets intrinsieker dan de mannen. Waar wel een verschil te constateren valt en dat niet te wijten is aan toeval is bij de amotivatie. Er is hier geen overlapping van de mediaan, uit de gegevens blijkt dat mannen iets minder gemotiveerd zijn dan vrouwen. 
 
Je had dus de goede conclusies getrokken.
