About the Units

The course content outlined below is organized into commonly taught units of study that provide one possible sequence for the course. Your teacher may choose to organize the course content differently based on local priorities and preferences.

Course Content

Unit 1: Exploring One-Variable Data and Collecting Data

You will formulate investigative questions, represent categorical and quantitative variables, compare distributions of one-variable data, interpret calculations to assess claims, and justify the use of experimental design principles.

Topics may include:

  • Variables
  • Tabular Representation and Summary Statistics for One Categorical Variable
  • Graphical Representations for One Categorical Variable
  • Graphical Representations for One Quantitative Variable
  • Summary Statistics for One Quantitative Variable
  • The Investigative Question Revisited and Data Collection
  • Random Sampling
  • Experimental Design

Unit 2: Probability, Random Variables, and Probability Distributions

You will build on understandings of simulated or empirical data distributions and fundamental principles of probability to represent, interpret, and calculate parameters for theoretical probability distributions for discrete random variables.

Topics may include:

  • Estimating Probabilities Using Simulation
  • Introduction to Probability
  • Mutually Exclusive Events 
  • Conditional Probability
  • Independent Events and Unions of Events
  • Introduction to Random Variables and Probability Distributions
  • The Binomial Distribution
  • The Normal Distribution

On The Exam

15%–25% of Score

Unit 3: Inference for Categorical Data: Proportions

You will use statistical inference to construct and interpret confidence intervals to estimate population proportions and perform significance tests to evaluate claims about population proportions, provided that appropriate conditions are met.

Topics may include:

  • Estimators
  • Sampling Distributions for Sample Proportions
  • Constructing a Confidence Interval for a Population Proportion
  • Setting Up a Test for a Population Proportion
  • Justifying a Claim Based on a Confidence Interval for the Difference Between Two Population Proportions
  • Carrying Out a Test for the Difference Between Two Population Proportions
  • Carrying Out a Chi-Square Test for Homogeneity or Independence

On The Exam

15%–25% of Score

Unit 4: Inference for Quantitative Data: Means

You will analyze quantitative data to make inferences about population means. You’ll discover how and why conditions for inference with proportions and means are similar and different.

Topics may include:

  • Sampling Distributions for Sample Means
  • Constructing a Confidence Interval for a Population Mean or Population Mean Difference
  • Setting Up a Test for a Population Mean or Population Mean Difference
  • Sampling Distributions for the Difference Between Two Sample Means
  • Justifying a Claim Based on a Confidence Interval for the Difference Between Two Population Means
  • Carrying Out a Test for the Difference Between Two Population Means

On The Exam

10%–20% of Score

Unit 5: Regression Analysis

You will explore relationships in two-variable quantitative data sets, assess correlation, and, if appropriate, use a linear model to predict values of the response variable from values of the explanatory variable.

Topics may include:

  • Graphical Representations Between Two Quantitative Variables
  • Correlation
  • Linear Regression Models
  • Least-Squares Regression
