You'r...Dear Michelle, thanks for your comments. You're right, not all exams have multiple choice. For the open questions similar techniques can be used (text mining) to detect fraud. These techniques are also used to detect plagiarism, for example to test if someone just copied a summary or thesis from the internet. Indeed the answers to the multiple choice questions were not stolen. The logical thing to do would be to ask someone that is an expert to answer the questions in advance and copy those which will lead to similar answer sequences which will be detected. I’m no expert in the legal implications, in my view these statistical tests indicate that something could be wrong and further investigations are required. @ORatWorkhttps://www.blogger.com/profile/09446587181442453824noreply@blogger.comtag:blogger.com,1999:blog-1537119231740022182.post-5310040069602204692013-07-09T10:56:07.924+02:002013-07-09T10:56:07.924+02:00That's interesting, but: not all (Dutch) exams...That's interesting, but: not all (Dutch) exams are multiple choice - the exams contain a lot of open questions. Secondly, the exams were stolen - not the answers. So the student must still find the answers him/herself and will still experience difficult questions. And will this statistical indication also be a valid proof of fraud? Michelle van Dijkhttp://www.michellevandijkschrijft.nlnoreply@blogger.com
