These are handwritten notes for the fourth topic of the new Analysis & Approaches HL (AAHL / A&A HL) course, for first exams in 2021 - statistics and probability. This has the 8 subtopics that are included in SL, plus an additional 10 subtopics for HL. There will also be significant overlap with the A&I Topic 3. I wrote and sold notes for the old IB courses, which have been fairly successful, so I am in the process of writing notes for the new courses, from scratch.
