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 exercises with solutions, a timed test with its answer key and an online quiz, all with a free PDF.
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.

3. Mean, Median, Standard Deviation and Outliers
Understand the mean and the median · Measure spread · Decide whether a value is an outlier
4. Five-Number Summary, Boxplots and Comparing Distributions
Understand the five-number summary · Draw a boxplot · Compare distributions · Read skew and outliers in a boxplot
5. z-Scores and the Normal Distribution
Understand a z-score · Understand the normal distribution · Find a normal probability · Work backward from a percentile
6. Two Categorical Variables and Two-Way Tables
Organize two categorical variables · Understand marginal, joint, and conditional relative frequencies · Decide whether two variables are associated
7. Scatterplots and Correlation
Understand a scatterplot · Describe a scatterplot · Understand the correlation coefficient
8. Least-Squares Regression and Residuals

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 exercise and test question has a worked solution, and every quiz answer has an explanation.
