Course Outline

SEMESTER ONE

Unit 1: Describing Data
Students take a pre-course assessment to be sure they are ready for the challenge of AP Statistics. They explore what statistics is, how it can be used, and how it's misused. They learn some basic statistics terminology, and look at the difference between counts and measures and the difference between descriptive and inferential statistics.

• What Is Statistics?
• Displaying Distributions with Graphs
• Describing Distributions Using Numbers
• Five-Number Summaries
• More on Describing Distributions

Unit 2: The Normal Distribution
Students learn about the normal distribution and the normal curve—a display of a normal distribution on a graph; the normal curve presents the normal distribution in a form that statisticians can use as a tool in inferential statistics. This unit addresses items in Topic III (The normal distribution) in the College Board's AP Statistics topic outline.

• Introduction to the Normal Distribution
• Standardized Scores
• Determining If a Data Set Is Normal

Unit 3: Bivariate Data
Students learn how statistics can be used to study how one variable affects another—for instance, do people who spend more years in school earn more money? Do people who take an experimental drug suffer fewer heart attacks? To answer questions like these, researchers need to gather data on two variables and then examine the data to see how the variables might be related. This unit addresses items in Topic I (Exploring bivariate data; Exploring categorical data: frequency tables) in the College Board's AP Statistics topic outline.

• Introduction to Bivariate Data
• The Least-Squares Regression Line
• The Correlation Coefficient
• Influential Points and Outliers
• Transformations to Achieve Linearity
• Categorical Bivariate Data: Two-Way Tables

Unit 4: Planning a Study
Students look at some of the most important issues in data gathering. They learn how this can make them smarter consumers of data; when they hear or read about studies, they will be able to determine whether or not they are valid. This unit addresses Topic II (Planning a Study) in the College Board's AP Statistics topic outline.

• Methods of Data Collection—Experiments and Studies
• Methods of Data Collection—Surveys

Unit 5: Probability
Students look at probability, which is vital for inferential statistics. They determine how likely it is that a sample really represents the population as a whole through proper sampling techniques and the laws of probability. This unit addresses items in Topic III (Law of large numbers; Addition rule, multiplication rule, conditional probability, and independence; Discrete random variables; Mean and standard deviation of a random variable) in the College Board's AP Statistics topic outline. Students review what they have learned and take the semester exam.

• What Is Probability?
• Introduction to the Basic Rules of Probability
• More on Conditional Probabilities and the Probabilities of Combined Events
• Probability Distributions
• Means and Variances of Random Variables
• Review and Exam

SEMESTER TWO

Unit 1: Binomials and Distributions

Students start to work with sampling distributions, which are distributions of possible sample means. This unit addresses items in Topic III (Sampling distribution of a sample proportion; Sampling distribution of a sample mean; Central Limit Theorem) in the College Board's AP Statistics topic outline.

• Introduction to Inferential Statistics
• Binomial Distributions
• Geometric Distribution
• Sampling Distributions: Means and Proportions

Unit 2: Introduction to Inference
Students look at concepts of sampling, probability, and distributions and are introduced to processes that researchers use to do statistical inference. This unit addresses items in Topic IV (The meaning of a confidence interval; Large sample confidence interval for a mean; Logic of significance testing; Large sample test for a mean) in the College Board's AP Statistics topic outline.

• Confidence Intervals for Means
• Statistical Significance and P-Value
• Significance and Hypothesis Testing: Means
• Errors in Hypothesis Testing

Unit 3: t Distribution for Means
Students review and reinforce many concepts that they may already know about statistical inference, learning a new dimension that's vital to anyone doing inferential statistics in the real world. This unit addresses items in Topic IV (Large sample confidence interval for a difference between two means; t distribution; Single-sample t procedures; Two-samplet procedures) in the College Board's AP Statistics topic outline.

• Confidence Intervals and Hypothesis Testing for a Single Mean
• Confidence Intervals for the Difference between Two Means
• Confidence Intervals and Hypothesis Tests for Two Independent Samples

Unit 4: Inference for Proportions
Students learn the basics of how to infer a population proportion based on a sample. This unit addresses items in Topic IV (Confidence intervals and significance tests for proportions and the differences between two proportions) in the College Board's AP Statistics topic outline.

• Confidence Intervals and Hypothesis Tests for a Single Population Proportion
• The Difference between Two Proportions

Unit 5: Inference for Tables and Least-Squares
Students build on what they've learned about analyzing bivariate sample data. They go beyond looking at the sample and make inferences about the population. This unit addresses items in Topic IV (Statistical Inference: Confirming Models) in the College Board's AP Statistics topic outline.

• One-Way Tables: Chi-Square for Goodness-of-Fit
• Two-Way Tables: Chi-Square for Association or Independence
• Inference for the Least-Squares Line

Unit 6: Final Preparation for the AP Statistics Exam
Students review what they have learned and take the final exam.

• General Preparation Strategies
• Strategies and Practice for Multiple-Choice and Free-Response Questions
• Putting It Together: Practice Exam and Mixed Practice
• Final Exam
