Goldie’s AP® Statistics UNIT 3 CURRICULUM | Inference for Categorical Data: Proportions | NEW 2026 CED

AP Statistics Unit 3 – Inference for Categorical Data: Proportions

Complete Unit Curriculum

 

This unit covers Inference for Categorical Data: Proportions in AP® Statistics and is fully aligned to the 2026-27 AP® Statistics CED. Students begin by exploring the sampling distribution of sample proportions and use this foundation to construct and interpret confidence intervals and perform hypothesis tests for a single population proportion. Students also examine Type I and Type II errors, statistical power, and the factors that influence the reliability of inference, building a comprehensive understanding of statistical decision-making.

 

Students then extend these ideas to comparing two population proportions through confidence intervals and hypothesis tests, learning to analyze and interpret differences between groups in real-world contexts. Throughout the unit, students practice checking inference conditions, interpreting p-values and confidence intervals, and communicating statistical conclusions in context. The unit concludes with chi-square tests for homogeneity and independence, allowing students to investigate relationships between categorical variables using two-way tables.

 

Whether you're a first-time AP® Statistics teacher or looking to streamline your prep with high-quality, editable resources, this bundle is designed to make planning, instruction, and assessment easier and more effective.
