AP Statistics (12th Grade) Math Worksheets, Lessons and Tests (Free PDF)
These ap statistics worksheets follow the College Board course chapter by chapter: each chapter has a lesson, a worksheet of at least 20 worksheet problems with solutions, a timed test with its answer key and an online quiz, all with a free PDF.

Key takeaway: AP Statistics follows the College Board course: exploring one- and two-variable data, collecting data with samples and experiments, probability and random variables, sampling distributions, confidence intervals and significance tests for proportions and means, chi-square tests and inference for regression slopes.

What students learn in AP Statistics
AP Statistics is a college-level introduction to statistics. Students learn to explore data, plan studies, use probability models and draw conclusions with statistical inference.
The course relies less on algebra than calculus does, and more on interpretation. For example, students must explain what a confidence interval means in context, or whether a p-value gives evidence against a claim. The course ends with the AP exam in May.
- Exploring data: distributions, summary statistics, and two-variable data with regression.
- Collecting data: sampling methods, bias, and experimental design.
- Probability: rules of probability, random variables, binomial and geometric distributions, and sampling distributions.
- Inference: confidence intervals and significance tests for proportions, means, chi-square, and slopes.
A year plan with these ap statistics worksheets
Start with describing data, then move to study design, because inference only makes sense with good data. Next, probability and sampling distributions build the theory. Finally, spend the second half on inference procedures and on writing conclusions in context.
How to use these ap statistics worksheets
Pick a chapter, read its one-page lesson, then solve the worksheet on paper and check every answer with the solutions page. Take the ten-question quiz to see what is still unclear, and finish with the timed test. Every page can be printed from its PDF button, and the quick practice at the bottom of each page gives ten new questions at every visit.
AP Statistics math: common questions
What is AP Statistics?
AP Statistics is a college-level statistics course taught in high school, usually in 11th or 12th grade, ending with the AP exam in May.
What units are in AP Statistics?
Nine units: one-variable data, two-variable data, collecting data, probability, sampling distributions, inference for proportions, inference for means, chi-square, and inference for slopes.
Is AP Statistics hard?
It needs less algebra than calculus but more careful reading and writing: every inference question asks for conditions, a calculation and a conclusion in context.
Are the answers explained?
Yes. Every worksheet worksheet problem and test question has a worked solution, and every quiz answer has an explanation.
Is AP Statistics easier than AP Calculus?
It uses less algebra, but it demands careful reading and writing. Many students find the computations easier and the interpretation harder, especially when a conclusion must be stated in context.
What calculator do you need for AP Statistics?
A graphing calculator with statistics functions is expected on the AP exam. It computes summary statistics, regressions, probabilities and inference tests, so students should practice with it all year.
