Main topics of ap exam

Main Topics & % of AP Exam

  • Section 1: Exploring Data (Looking for and explaining trends and patterns in data – 20-30%)

  • Section 2: Sampling and Experimentation (planning and conducting a study(10-15%)

  • Section 3: Anticipating patterns (exploring random phenomena using probability and simulation – 20-30%)

  • Section 4: Statistical Inference (estimating population parameters and hypothesis testing -- 30-40%)


Section 1 exploring data

Section 1: Exploring Data

Looking for and explaining trends and patterns in data

  • Exploring one variable data sets (center, spread)

  • Comparing one-variable distributions (graphs, shape, center/spread, outliers, clusters, gaps)

  • Exploring two-variable data sets(linearity, association, residuals, transformations)

  • Exploring categorical data (frequency tables, bar charts, marginal frequencies, conditional frequencies, association)


Section 2 sampling and experimentation

Section 2: Sampling and Experimentation

  • Overview of data (methods of data collection—census, survey, experiment, observation)

  • Planning and conducting a study(what counts as data, how data will be analyzed, population vs sample, random selection, bias, sampling methods)

  • Planning and conducting an experiment(what counts as data , how data will be analyzed, treatments, controls, bias, confounding, blinding, randomization)

  • Generalizabilityand drawing conclusions.


Section 3 anticipating patterns

Section 3: Anticipating patterns

  • Probability.Concept of uncertainty, law of large numbers, independent, conditional, distributions, random variables

  • Combining independent random variables. Descriptive stats for sums /differences of independent random variables

  • Normal Distribution. Properties, tables, modeling with normal distribution

  • Sampling Distributions. Sample proportion, sample mean, central limit thm, t-distribution, chi-square distribution


Section 4 statistical inference hypothesis testing

Section 4: Statistical Inference & Hypothesis Testing

  • Point Estimation and confidence intervals. Population parameters and confidence intervals – proportions, difference between 2 proportions, means, difference between means, bias, variability, slope of regression line

  • Tests of significance. Null and alternative hypotheses, Type 1 & Type 2 errors, power, tests for proportions, tests for mean, Chi-square test for goodness of fit, test for slope of least square regression line
