AP Statistics
DATA · PROBABILITY · STATISTICAL INFERENCE
The college-level introduction to reasoning with data: how to collect it, describe it, model chance, and draw conclusions that hold up. It is the equivalent of a first-semester university statistics course, and useful to almost every future major, from economics and psychology to medicine, engineering and computer science.
Five units, one way of reasoning
| Unit | Content | Key topics | MCQ weight |
|---|---|---|---|
| 01 | Exploring One-Variable Data & Collecting Data | Graphs and summary statistics, z-scores, the normal distribution, sampling methods, experimental design, bias | 20–30% |
| 02 | Probability, Random Variables & Probability Distributions | Probability rules, conditional probability, discrete and continuous random variables, the binomial distribution | 15–25% |
| 03 | Inference for Categorical Data: Proportions | Sampling distribution of a proportion, confidence intervals, significance tests, chi-square tests | 15–25% |
| 04 | Inference for Quantitative Data: Means | Central Limit Theorem, t-procedures for one mean, two independent means and matched pairs | 10–20% |
| 05 | Regression Analysis | Scatterplots, correlation, least-squares regression, residuals, r², interpreting slope and intercept | 10–20% |
42 multiple-choice
Four answer choices per question.
4 free-response
Full written statistical reasoning, 10 points each.
Content follows College Board’s revised AP Statistics Course and Exam Description (effective Fall 2026, first assessed May 2027).
How the course runs
Students will not be handed tricks that fall apart on an unfamiliar question; they learn the real statistics, the kind that still works in a university lecture hall.
Core concept
Where the idea comes from and why it is true.
Worked reasoning
Seeing the idea applied carefully, step by step.
Problem solving
Using it on new problems, then on exam-style questions.
| Weeks | Focus | Sessions |
|---|---|---|
| 1–4 | Unit 1 · One-variable data & collecting data | 8 |
| 5–8 | Unit 2 · Probability & random variables | 8 |
| 9–12 | Unit 3 · Inference for proportions | 8 |
| 13–15 | Unit 4 · Inference for means | 6 |
| 16–17 | Unit 5 · Regression analysis | 4 |
| 18–20 | Exam preparation · full mock exams, timing and free-response writing | 6 |
Theory
New concepts from first principles: definitions, intuition and the logic behind each method, with short checks for understanding during class.
Recitation
Problem sets on the week’s theory, worked together; practice writing complete free-response answers; common mistakes corrected before they settle in.
