AP Statistics Practice Test

Build AP Statistics readiness with original data analysis, probability, inference, regression, and statistical communication questions.

AP Statistics practice sets

This page combines AP Statistics preparation in one canonical hub. It provides five short practice sets with 10 original questions each, covering one-variable data, data collection, probability, random variables, categorical and quantitative inference, regression, digital exam strategy, and statistical writing.

Skills covered

  • Explore data — distributions, graphs, summary statistics, standard deviation, z-scores, and outliers
  • Collect data — random sampling, experiments, confounding, bias, and scope of conclusions
  • Probability — conditional probability, independence, binomial settings, normal models, and simulation
  • Inference — confidence intervals, significance tests, proportions, means, conditions, p-values, and errors
  • Regression — residuals, correlation, slope, r², extrapolation, and model interpretation

AP Statistics course and exam scope

College Board organizes current AP Statistics content into five units: Exploring One-Variable Data and Collecting Data; Probability, Random Variables, and Probability Distributions; Inference for Categorical Data: Proportions; Inference for Quantitative Data: Means; and Regression Analysis. The course emphasizes formulating questions, collecting data, analyzing data, and interpreting results.

College Board’s current exam page describes a fully digital exam in Bluebook with multiple-choice and free-response questions. Current College Board information also includes a calculator policy and digital response guidance; exam details and course revisions can change, so review the current official materials before test day.

How to use this page

Start with one untimed set to identify a topic gap, then use timed sets to build pacing. For every missed item, identify the variable and parameter, check the conditions, read the explanation, and write a new conclusion in context.

These questions are original supplemental practice. They are not official College Board questions, secure AP Exam content, AP Classroom assignments, a score predictor, or a substitute for current AP policies and course materials.

For current scope and preparation, review the AP Statistics course page, the AP Central course overview, the AP Statistics exam page, the AP Statistics Course and Exam Description, and the AP calculator policy.

1. QuestionMultiple choice

Which four broad stages describe the statistical problem-solving process?

Please select an answer first.

Correct answer: A

The correct answer is Formulate questions, collect data, analyze data, and interpret results.

  1. Identify the statistical task: Determine whether the question asks you to describe data, model probability, collect data, or make an inference.
  2. Apply the method: The AP Statistics framework emphasizes a complete statistical investigation process.
  3. Interpret the result: State the conclusion in context and check the variable, population, sample, units, and conditions.

The AP Statistics framework emphasizes a complete statistical investigation process.

2. QuestionMultiple choice

Why must a free-response conclusion be written in context?

Please select an answer first.

Correct answer: B

The correct answer is The meaning of a statistical result depends on the population and variable being studied.

  1. Identify the statistical task: Determine whether the question asks you to describe data, model probability, collect data, or make an inference.
  2. Apply the method: Statistical reasoning requires connecting calculations to the real question.
  3. Interpret the result: State the conclusion in context and check the variable, population, sample, units, and conditions.

Statistical reasoning requires connecting calculations to the real question.

3. QuestionMultiple choice

Which statement is best when a test has p-value 0.18?

Please select an answer first.

Correct answer: C

The correct answer is There is not enough evidence to reject the null hypothesis at α = 0.05.

  1. Identify the statistical task: Determine whether the question asks you to describe data, model probability, collect data, or make an inference.
  2. Apply the method: A p-value of 0.18 exceeds 0.05, so the result is not statistically significant at that level.
  3. Interpret the result: State the conclusion in context and check the variable, population, sample, units, and conditions.

A p-value of 0.18 exceeds 0.05, so the result is not statistically significant at that level.

4. QuestionMultiple choice

According to current College Board information, what should students verify before an AP Statistics exam?

Please select an answer first.

Correct answer: D

The correct answer is The current digital format, calculator policy, reference information, and response procedures.

  1. Identify the statistical task: Determine whether the question asks you to describe data, model probability, collect data, or make an inference.
  2. Apply the method: Exam delivery and policies can be updated, so current College Board guidance matters.
  3. Interpret the result: State the conclusion in context and check the variable, population, sample, units, and conditions.

Exam delivery and policies can be updated, so current College Board guidance matters.

5. QuestionMultiple choice

What is a useful practice routine for interpreting computer output?

Please select an answer first.

Correct answer: A

The correct answer is Identify the parameter, method, estimate, standard error or interval, and conclusion.

  1. Identify the statistical task: Determine whether the question asks you to describe data, model probability, collect data, or make an inference.
  2. Apply the method: A structured reading of output helps connect values to the statistical question.
  3. Interpret the result: State the conclusion in context and check the variable, population, sample, units, and conditions.

A structured reading of output helps connect values to the statistical question.

6. QuestionMultiple choice

Why should a student check randomization or sampling details in a study?

Please select an answer first.

Correct answer: B

The correct answer is They determine what conclusions about cause, population, or generalization are justified.

  1. Identify the statistical task: Determine whether the question asks you to describe data, model probability, collect data, or make an inference.
  2. Apply the method: Design determines the scope of valid conclusions.
  3. Interpret the result: State the conclusion in context and check the variable, population, sample, units, and conditions.

Design determines the scope of valid conclusions.

7. QuestionMultiple choice

Supplemental practice must be distinguished from official content and scoring.

8. QuestionMultiple choice

Which graph feature should be checked before describing a distribution?

  1. Identify the statistical task: Determine whether the question asks you to describe data, model probability, collect data, or make an inference.
  2. Apply the method: Condition checks justify the method before the calculation is interpreted.
  3. Interpret the result: State the conclusion in context and check the variable, population, sample, units, and conditions.
