This AP Statistics study guide covers multiple-choice and free-response question strategies, focusing on inference, study design, sampling distributions, and probability. Key concepts include selecting appropriate procedures (t-tests, z-tests, chi-square), interpreting p-values and confidence intervals, and applying the SPDC template (State, Plan, Do, Conclude) for free-response questions. Special cases like matched pairs and two-sample t-tests are also addressed.
