Subtitles of the Movie

In this movie we'll go through another practice exam question focusing on the strategy of answering the questions. Our question for review is as follows: Which of the following best describes continuous distributions? Is it A: A probability distribution type that displays three point estimates; B: A type of probability distribution that shows uncertainty in values; C: A probability distribution that may have a probability of zero; or D: A type of probability distribution that is based on a whole number? If the answer doesn't jump out at you immediately, then the first thing you can do is go through the process of elimination. If you look closely the only one that is an incorrect statement is D. A continuous distribution is not based on a whole number; that's discrete distributions. Continuous distributions can have values that are infinitely indivisible, so let's cross that off and we now have three remaining statements that are all accurate in terms of continuous distributions. Here's another note that would help. One thing you will see are characteristics that don't necessarily describe the technique or document in question. For instance, with option A, continuous distributions certainly can display three-point estimates, but would you say that the statement describes what a continuous distribution is, or its purpose? Well, not necessarily. Also, continuous distributions display more than just three-point estimates, although the statement is still accurate since they can, and often do, display these estimates. Since this is just a characteristic let's mark it and move on to the next one. Option B doesn't seem like a characteristic. It's a true statement and it seems to describe continuous distributions overall. Option C is a characteristic. It simply states accurately that a continuous distribution may have a probability of zero. Not always but sometimes and based on what we've gone through, option B is the best choice. If you've taken the PMP Exam you're a few steps ahead of the curve in preparing for this Exam. This is not meant to dissuade those who have not taken a PMI Exam before, but the reason I say this is that the structure of the questions is similar to what you see in the PMP Exam. Also, the foundation that you have of the entire PMBOK Guide does help as well. Let's go through a few extra notes to go along with your Workbook in regard to the Exam questions. Keep the following in mind: Expect situational questions; expect what-comes-next questions; and expect questions that say except, best, and most likely; and finally, don't rely on memorization or memorizing definitions alone. You need to understand what the definitions mean. This is because you'll need to analyze situations or understand what is going on within a scenario based on recognizing a technique that's being used, or recognizing what process you're in. I hope that's helped you in getting into the Exam mindset. As I mentioned previously, the best thing you can do is to go through as many risk-related exam questions that you can get your hands on and focus your studies on the areas where you find you are the weakest. And that wraps up this review of the Workbook exercises and exam-taking strategies. This also brings this section to a close.
