Abstract:
The purpose of the present study was to evaluate various analytical means to detect academic cheating in an experimental setting. The omega index was compared and contrasted given a gold criterion of academic cheating which entailed a discrepant score between two administrations using an experimental study with real test takers. Participants were 164 elementary school students who were administered a mathematics exam followed by an equivalent mock exam under conditions of strict and relaxed, invigilation, respectively. Discrepant scores were defined as exceeding 7 responses in any direction (correct or incorrect), based on what was expected due to chance. Results indicated that the omega index was successful in capturing more than 39% of the cases who exceeded the conventional plus or minus 7 discrepancy criteria. It is concluded that the response similarity analysis may be an important tool in detecting academic cheating.
