What does holistic grading mean for you? Basically, you can't expect to earn many points by including a few correct equations or arithmetic answers if you're missing key statistical analysis. You need to show you understand how to use stats to get a good score on these questions.

So instead of trying to get a point here and there by including a correct formula or solving one part of a question, make sure you're looking at the entire problem and answering it as completely as possible. Also, if you need to include an explanation, be sure it explains your thought process and the steps you took. If your explanation shows you understand important stats concepts, it could help you get a higher score even if your final answer isn't perfect.
Aiming for the most complete response possible is also important if you can't answer one part of a question that's needed to answer other parts. For example, if you can't figure out what the answer to part A is, but you need to use that answer for parts B and C, just make up an answer (try to keep it logical), and use that answer to solve the other parts, or explain in detail how you'd solve the problem if you knew what the answer to part A was. If you can show you know how to solve the latter problems correctly, you'll likely get some credit for showing you understand the stats concepts being tested.
Knowing how to solve common stats functions on your calculator and interpret the answers you get will save you a lot of time on the exam. Your calculator will likely be most useful on the multiple-choice section where you don't need to worry about showing work. Just plug the data you're given into your calculator, and run the right equations. Then you'll have your answer!
Before the AP Stats exam, you should know all important terms like the back of your hand. Having a general idea isn't good enough. A big part of stats is being able to support your answers, and to do this you'll often need to use stats vocab in your explanations. Just stating the term won't earn you nearly as many points as being able to explain what the term is and how it supports your answer, so make sure you really know your vocab well.
The AP Statistics exam is three hours long and consists of 40 multiple-choice questions and six free-response questions. To prepare well for AP Stats exam questions, it's important to take practice exams and know how to grade them so you can estimate how well you'd do on the actual test. When studying for the AP exam, remember to answer the entire question for free response, know how to use your calculator, and be on top of stats vocabulary. 2ff7e9595c
