The AP Statistics Exam is as much about knowing which formulas to use as it is about understanding the data. The good news? The College Board provides a formula sheet during the test.
In this guide, we’ll cover:
- What’s on the AP Stats formula sheet
- How to interpret each formula
- Which formulas you still need to memorize
- How to practice applying them under exam conditions
- How RevisionDojo can help you turn formulas into higher scores
What Is the AP Stats Formula Sheet?
The AP Statistics formula sheet is a two-page reference guide you’ll have during both sections of the exam. It includes:
- Probability formulas
- Statistical symbols
- Sampling formulas
- Hypothesis testing formulas
- Graph interpretations
- Common distributions
It’s designed to help you apply math correctly without wasting time memorizing every formula.
Key Formulas You’ll Find
Here are some categories and examples you can expect:
1. Probability
- P(A∩B)=P(A)P(B∣A)P(A \cap B) = P(A)P(B|A)
- Complement rule: P(A′)=1−P(A)P(A') = 1 - P(A)
2. Descriptive Statistics
- Mean: xˉ=∑xn\bar{x} = \frac{\sum x}{n}
- Standard deviation formula
3. Sampling Distributions
- Standard error: SE=σnSE = \frac{\sigma}{\sqrt{n}}
4. Confidence Intervals
- xˉ±z∗σn\bar{x} \pm z^* \frac{\sigma}{\sqrt{n}}
5. Hypothesis Testing
- Test statistic for proportions and means
What’s Not on the Formula Sheet
- How to choose the right formula for a situation
- Concept explanations
- Step-by-step worked examples
That’s why practice is essential — the formula sheet won’t help if you don’t know when to use each formula.
How to Use the AP Stats Formula Sheet Effectively
- Familiarize Yourself Early — Download it months before the exam.
- Annotate While Studying — Make notes about when to use each formula.
- Practice Under Timed Conditions — Simulate real test pressure.
- Link to Question Types — Match each formula to the types of FRQs and MCQs where it appears.
- Combine With Past Exams — Build familiarity with real College Board questions.
