Volgens mij moet de conclusie hier zijn dat de studenten beter OF slechter scoren op hun post test 2 als op hun pretest aangezien de nulhypothese niet verworpen wordt en uit vraag 1 hypothese 3 blijkt dat dit betekend dat het resultaat gewoon niet hetzelfde is als deze van de pretest (niet noodzakelijk enkel een beter resultaat)
