If you’re preparing for the AP Statistics exam, one of your best friends on test day is the AP Stats Formula Sheet. Provided by the College Board, this sheet contains essential formulas and statistical tables you’ll need during the exam. But here’s the thing — simply having the sheet isn’t enough. To score high, you must know when and how to use each formula.
In this guide, we’ll cover:
- What’s on the AP Stats Formula Sheet
- How it’s organized
- Strategies for using it efficiently during the exam
- Common mistakes to avoid

What’s on the AP Stats Formula Sheet?
The AP Statistics Formula Sheet includes:
1. Probability and Statistics Formulas
- Mean and standard deviation (population & sample)
- Variance formulas
- z-scores and standardization
2. Regression Formulas
- Least-squares regression line
- Slope, intercept, and residual formulas
3. Probability Rules
- Addition and multiplication rules
- Conditional probability
4. Inference Formulas
- Confidence intervals for means and proportions
- Hypothesis testing formulas
5. Statistical Tables
- z-table (standard normal distribution)
- t-table (Student’s t-distribution)
- Chi-square distribution table
How to Use the Formula Sheet Effectively
1. Know It Before Exam Day
Don’t rely on reading it for the first time during the exam. Familiarity saves time.
2. Pair Formulas with Context
Know which problems require which formulas — for example, using a t-distribution instead of a z-distribution for small samples.
3. Use It for Accuracy Checks
Even if you remember formulas, the sheet ensures you don’t make sign or coefficient errors.
4. Practice Under Timed Conditions
Integrate the sheet into your practice exams so it feels natural to use.
Common Mistakes Students Make
- Over-reliance on the sheet: You still need conceptual understanding.
- Misinterpreting statistical tables: Make sure you know whether to use one-tailed or two-tailed values.
- Forgetting units and context: The formula may give a number, but you must interpret it correctly.
AP Stats Exam Format (Quick Recap)
- Section I (50% of score): 40 multiple-choice questions
- Section II (50% of score): 6 free-response questions (including an investigative task)
Knowing how to use the formula sheet is especially valuable in Section II, where you must justify your answers with calculations.
