WST01 Representation and summary of data Topic Questions
Every WST01 Representation and summary of data topic question from the 2014–current syllabus, drawn from 36 papers (2014–2026) and grouped by syllabus point. Each row opens a page listing the exact question numbers, marks and a direct link into the paper. These are questions by topic, not full papers, so you can revise one topic at a time.
Core finding
2.2 Measures of location mean, median, mode. is the most frequently assessed subtopic in Representation and summary of data, with 112 topic questions and 253 marks across 36 papers. 2.1 Histograms, stem and leaf diagrams, box plots. follows with 106 topic questions and 260 marks. The topic contains 4 subtopics, 270 topic questions and 629 marks in total. Rows count only the parts tagged to that subtopic, keep the same colour in both charts and repeat paper count, tagged marks and year range in the native table.
Topic question count and mark distribution
Subtopics are on the vertical axis and sorted from highest to lowest. Only the parts whose knowledge graph matches a subtopic are counted for it, and percentages are each row's share of the tagged total in that chart. A part tagged to several subtopics is counted in each bar, so the bars are not a partition of the topic total.

Topic question rules and edge cases
- How many subtopics does Representation and summary of data contain?
- This page lists 4 subtopics tagged to the current syllabus. They are ordered by syllabus number, then alphabetically, and each row opens a page of matching past-paper questions.
- How are the subtopic question and mark totals calculated?
- A multiple-choice question contributes one item and its marks to every subtopic it is tagged with. A structured question contributes one item per tagged part, and that part’s marks; untagged parts of the same question are not counted here. A part tagged to several subtopics therefore appears under each of them.
- Why do some subtopics have no numbered prefix?
- Practical-skills statements and some syllabus bullets are unnumbered. Numbered statements come first; unnumbered statements and ties are sorted alphabetically.
- Is the LaTeX rendered without JavaScript?
- Yes. Subtopics that contain formulas are converted to static KaTeX HTML during the build, and the KaTeX stylesheet is served from the same site.
