IB Maths AA SL Ch 7 Bivariate Statistics: Unit of 4 Lessons + Test + SOW (Analysis and Approaches)

IB Maths AA SL (Analysis and Approaches): Bivariate Statistics, 4 lessons.

A complete, ready-to-teach unit for Chapter 7 of the IB Mathematics: Analysis and Approaches SL course (Statistics: bivariate data), following the section order of the Oxford AA SL course book. Four full lessons, a practice booklet, a 60-mark unit test and a scheme of work. Every question is original and written in IB exam style.

What is included

1. Lesson PowerPoint (90 slides, fully animated, every step appears on click) with a clickable contents page:

• 7.1 Scatter diagrams
• 7.2 Measuring correlation (Pearson’s r)
• 7.3 The line of best fit
• 7.4 Least squares regression (y on x and x on y)

Every lesson follows the same routine: Do Now with solutions, teach-ins with diagrams, step-by-step worked examples, a lesson plenary with answers, and an IB exam-style Exit Ticket (Paper 1 or Paper 2) with a full M/A/R markscheme and the command term explained.

1. Practice booklet (PDF) with questions for every section, plus a separate full answer key.
