How to Approach AP Statistics Multiple-Choice Questions?

The best way to prepare for the MCQ section is to practice. Beyond learning the material through class or on your own, going through many practice questions will help prepare you for the pace of the exam as well as the types of questions that will show up on the exam. For this reason, the best types of practice questions are high-quality ones that are similar to the types of questions that you will encounter on the AP Statistics exam.

Here are some tips for approaching the individual questions on the MCQ section of the AP Statistics exam:

  1. Read the question and answer choices thoroughly

    The first thing you should do on any MCQ is carefully read the question. Then scan through the answer choices to see what form the answer will be in. For example, sometimes the question will include an integral and the answers will be numbers, requiring you to calculate the result of the integral. Other times, the answers will be in integral notation, so computing the integral will waste time.

  2. Underline important information

    When reading through the question stem, underline things like vocabulary, given values, function definitions, and the actual quantity the question is asking for. This will help you key in on the important aspects of the question. When you hit a vocabulary word, stop and analyze what that means. For example, if the question says “median,” take a moment to think about what that means in calculus, like “dividing place between halves of a dataset,” “center of the dataset,” and so on.

  3. Eliminate answer choices

    Sometimes you can immediately eliminate a choice because it does not fit in with what the question is asking. Cross out any such choices in your test booklet. For example, if the question asks you to interpret a p-value, you can eliminate choices that do not mention a null hypothesis.

  4. Keep moving

    If you do not immediately know how to solve a problem, it’s OK to skip it and come back later. The AP Statistics exam is a timed test. Therefore, it is crucial to not waste time on questions you do not know until you’ve made sure to answer the ones you do know. Fold the corner of the page in your question booklet to mark the pages you need to come back to. You can even mark the ones you answered but aren’t sure of by folding the corner of the page in your question booklet. Then, if there is time, at the end of the exam, revisit all of the pages you marked to either try to answer the question or double-check your answer, unfolding the page corners as you revisit them.

  5. Read the question again

    Sometimes, when you get into the thick of computing things, you tend to forget the gist of the question. Before answering, reread the question to find what you are supposed to calculate (if you underlined, it should be easy to find). Then compare it to help you ensure that you haven’t forgotten the final steps.

  6. Check before you bubble

    Every time you answer a question, compare your answer sheet to the test booklet to make sure you’re answering the right question. This is especially important if you skip a question that you don’t know how to answer, but it is good practice regardless. If your answer sheet gets misaligned with the test booklet, you may end up missing points that you otherwise would have gotten.
