IGCSE Booklet 32 - Statistics | Original 35-page PDF

Download Dr Taylan Çeltik’s original 35-page IGCSE Booklet 32 - Statistics, covering pie charts, data displays, scatter diagrams, summary statistics, grouped mean estimates, cumulative frequency, quartiles and unequal-width histograms.

This is the original teaching booklet, retaining its historical question numbers, diagrams, equations and included selected worked examples. It is not a newly authored complete solutions pack. Digital PDF download only.

A separate clarification PDF is included. Page 15, data types: discrete data have a countable set of possible values; the values need not all be integers. The counting examples in the original remain valid. Page 22, cumulative frequency: the third total is 25 + 19 + 23 = 67, so the small right-margin addition should be 44 + 23, rather than 44 + 13. The complete table gives the correct total 67; the outer annotation is tightly cropped in the original. Pages 24–25, unequal-width histograms: use frequency density = frequency/class width on the vertical axis. Page 24’s preliminary grids are labelled frequency; the corrected density scale is shown on page 25. Page 31, Question 1(c)(ii): the first regrouped interval is 0 to 30 seconds, with frequency 20. Its width is 30 and its frequency density is 20/30 = 2/3, not 1. The worked scan on page 30 uses the correct interval and density; page 31’s summary table and histogram do not.

Historical scanned worked examples are softer than the typed text. All page content remains in its original positions. The right-margin annotation on page 22 is cropped in the original; the data table is complete and the separate clarification supplies the correct addition.

Use the exact question/page references in each matching video description. The booklet includes further practice beyond each selected recording. Spiral learning connects these skills with earlier number, algebra, graph and geometry ideas.
