AP Statistics introduces students to the major concepts and tools for collecting, analyzing and drawing conclusions from data. According to surveys of comparable curricula at four-year colleges and universities, it is equivalent to a one-semester, non-calculus-based college course in statistics.

Topics covered on the exam include:

Exploring Data: Describing Patterns and Departures from Patterns (20%–30%)

  • Constructing and interpreting graphical displays of distributions of univariate data (dotplot, stemplot, histogram, cumulative frequency plot)
  • Summarizing distributions of univariate data
  • Comparing distributions of univariate data (dotplots, back-to-back stemplots, parallel boxplots)
  • Exploring bivariate data
  • Exploring categorical data

Sampling and Experimentation: Planning and Conducting a Study (10%–15%)

  • Overview of methods of data collection
  • Planning and conducting surveys
  • Planning and conducting experiments
  • Generalizability of results and types of conclusions that can be drawn from observational studies, experiments and surveys

Anticipating Patterns: Exploring Random Phenomena Using Probability and Simulation (20%–30%)

  • Probability
  • Combining independent random variables
  • The normal distribution
  • Sampling distributions

Statistical Inference: Estimating Population Parameters and Testing Hypotheses (30%–40%)

  • Estimation (point estimators and confidence intervals)
  • Tests of significance
