Statistics has me a bit on edge with the AP exam approaching. What topics do you all feel are the most critical to understand before taking the AP Statistics exam? And are there types of questions that come up more often that I should practice extra?
It's completely normal to be nervous before a big exam like the AP Statistics, but you're doing the right thing by preparing in advance! The AP Statistics exam tends to focus heavily on interpreting data, including descriptive statistics and how to properly display that data. Make sure you're comfortable with statistical graphs and charts, means, medians, modes, and standard deviation.
Inferential statistics is another core topic. This includes understanding how to design experiments, sampling methods, and most notably, calculating confidence intervals and performing hypothesis tests. Be especially familiar with different distributions, like binomial and normal distributions, and how to use your calculator effectively for these.
As for question types, you'll encounter both multiple-choice questions and free-response questions. The free-response section often features real-world problems that require you to set up and interpret the results of statistical tests. My advice would be to practice these types of problems, as well as review past exams and practice using the formulas and calculator functions. The CollegeBoard website has past free-response questions with scoring guidelines that you can use to assess your understanding and preparation.
