A teacher wants to administer a multiple choice (each question having six choices) based quiz of high difficulty level to class of 60 students. The quiz has 60 questions. The probability of selecting the correct answer for good answer for a good student and a brilliant student was 0.2 and 0.25, respectively. The poor students had no learning advantage. The teacher did not want students to cheat but does not have time and resource monitor. All students were seated serially in 10 rows and 6 columns. Is it possible for the teacher to detect cheating without monitoring? Choose the statement that best describes your opinion (a) it is not at all possible, teacher will have to introduce technology, if there is no human support (b) it is always possible but teach has to calculate the exact answer (c) it is possible when many students sitting next to each other have the same incorrect answers for multiple questions. However, there can be a small error in judgement. (d) it is possible when many students sitting next to each other have the same correct answer for multiple questions. However, there can be a small error in judgement. |
