Hi, I am an instructor (adjunct) at a community college. I was wondering if you could help me figure out the likelihood of cheating on a test. I caught two students cheating on a scantron test. There were 50 multiple choice questions. 5 choices for each question. Both students got the same 16 wrong answers and selected the same incorrect answer. (The students had the same exact wrong choices) My question - Did these students cheat? Statistical? They sat together and no one else in the class had the same incorrect scantrons answers. Please respond. Thanks in advance iLUSiON - le plus grand de tous http://cyworld.nate.com/ilusion |
