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

A complete, ready-to-teach unit for IB Mathematics: Analysis and Approaches SL, Chapter 6: Statistics for univariate data. One editable PowerPoint covers all four lessons, plus a practice booklet, answer key, 60-mark unit test with markscheme and a scheme of work.

Written by an experienced IB Maths lead teacher and exam marker. The unit follows the section order of the Oxford AA SL course book (2019), so it slots straight into your scheme, but every question is original.

What’s included

• Chapter deck (93 slides, PowerPoint): a clickable contents page jumps to each lesson, with a “back to contents” button on every lesson title slide
• Practice booklet (PDF): one section per lesson, with space to work
• Full answer key (PDF), including graphs
• End-of-unit test (PDF): 60 marks, Section A no calculator (Paper 1 style) and Section B GDC (Paper 2 style)
• ����Vlogt markscheme (PDF) with IB-style M, A and R marks
• Scheme of work (Word): objectives, IB syllabus links, Do Now, worked examples, Exit Ticket and GDC focus for every lesson

Lessons

1. 6.1 Sampling (populations and samples, discrete and continuous data, sampling methods, bias)
2. 6.2 Presentation of data (histograms, cumulative frequency graphs, percentiles, box-and-whisker plots)
3. 6.3 Measures of central tendency (mean, median and mode from lists, frequency tables and grouped data)
4. 6.4 Measures of dispersion (range, IQR, variance, standard deviation, outliers, effect of constant changes)

Every lesson follows the same structure

• Do Now: four retrieval questions plus an extension, with handwritten solutions
• Teach-in slides with colour-coded graphs and diagrams, and steps that appear one click at a time
• Worked examples: the question on one side, the solution building line by line on the other
• Lesson plenary with a “spot the mistake” question and an answers slide
• Exit Ticket: an IB exam-style question with marks, followed by the markscheme so students can self-mark

All maths is properly typeset with stacked fractions, and every answer has been checked. The essential question and IB syllabus reference sit at the top of every slide.

Covers IB AA SL syllabus 4.1, 4.2 and 4.3.

Fonts: the deck uses three free Google Fonts (Baloo 2, Lora and Nothing You Could Do). Install them for the intended look; the slides still work without them.
