Goldie’s AP® Statistics UNIT 2 CURRICULUM | Probability and Random Variables

AP Statistics Unit 2 – Probability, Random Variables, and Probability Distributions
Complete Unit Curriculum

This unit covers Probability, Random Variables, and Probability Distributions in AP® Statistics and is fully aligned to the 2026–2027 AP® Statistics CED. Students develop a strong foundation in probability by learning how to calculate and interpret basic probabilities, conditional probability, and probabilities involving unions and intersections of events.

The unit also introduces two-variable categorical data, where students analyze relationships using side-by-side bar graphs, segmented bar graphs, mosaic plots, and conditional relative frequencies. Students then extend their understanding to random variables and probability distributions, including both discrete and continuous cases, as well as binomial and normal distributions. The unit concludes with an introduction to sampling distributions, preparing students for statistical inference in future units.

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.
