This video is part of the official Stats Medic AP Stats Exam Review Course. Download a printable version of this list here:
1: Clearly communicate your understanding
Your AP score is a combination of your understanding of statistical content, but also how well you can communicate your understanding of the content. Don't expect AP graders to know what you are thinking. Write it down!
2: Always include context in your answers
Every one of the free response questions will be framed with a different context. Be sure that AP Exam graders can identify the context of the problem just by reading your response. Examples: "The distribution of Robin's tips", "convincing evidence that there is an association between age-group and gender" and "the y-intercept tells us the predicted wait time when there are 0 customers in line."
3: Be precise in your language and vocabulary
A big part of clearly communicating your understanding is to use the correct vocabulary. You will be marked down for using the incorrect or inappropriate vocabulary terms. Don't say "stratified" when you mean "block design". If you are not exactly sure on the correct vocabulary term, simply describe the idea.
4: Use appropriate notation
Notation matters! Make sure you know the correct notation for each statistic and for each parameter. You will be marked down for using incorrect notation.
Statistics: phat, xbar, s.
Parameters: p, mu, sigma
5: Do not rely on your calculator
On the free response, you are always better off to show a formula and your work. Try to use your calculator only to check your final answers. Here is a summary of the calculator functions you might use on the AP Exam.
6: Manage your time
You have 90 minutes for 40 multiple choice questions (easy) and 90 minutes for 6 free response questions (harder). For the free response questions, plan to spend an average of 13 minutes on each of questions #1 - 5 and then 25 minutes on question #6 - the Investigative Task.

7: Do not leave anything blank
There is no penalty for guessing on the multiple choice, so you should NEVER leave any blank. If you are struggling on a free response question, write down anything that you know...even if it's just a formula. There is a chance you could earn partial credit.
8: Know the formula sheet
You don't want to spend valuable exam time searching through the formula sheet looking for what you need. Check out this blog post to get a detailed description of the AP Statistics Exam Formula Sheet.
9: Know your inference
