A common tip for taking multiple-choice tests is to always pick (b) or (c) if you are unsure. The idea is that instructors tend to feel the answer is more hidden if it is surrounded by distractor answers. An astute statistics instructor is aware of this and decides to use a table of random digits to select which choice will be the correct answer. If each question has ﬁve choices, use Table I in Appendix A or a random-number generator to determine the correct answers for a 20-question multiple-choice exam.
