Unit 4 - Statistics and Probability

Unit 4 develops the critical skills of data analysis, interpretation, and probabilistic reasoning that are central to IB Math AI. These resources follow the official IB syllabus and are written to reflect the language, notation, and question styles students will encounter on their exams. Each subtopic—whether it’s data collection, correlation, conditional probability, or normal distributions—is introduced with conceptual clarity and built up toward IB-style applications. From guided notes and accessible explanations to real-world examples, practice sets, and exam-style assessments, every resource has been classroom-tested to strengthen student understanding, confidence, and readiness for both internal and external IB assessments.
