Prior knowledge

Students would benefit from having some previous experience of working through the data-handling cycle (possibly as part of their GCSE mathematics course), but there are no true prerequisites for this piece of work.

+
Relevance to Core Maths qualifications

  • AQA
  • C&G
  • Eduqas
  • Pearson/ Edexcel
  • OCR

+
Suggested approaches

This task is suitable for whole-class presentation and student discussion. Students can work in pairs on the categorisation activities that are included within the presentation.

+
Resources/documentation

The PowerPoint presentation includes brief teacher instructions, in the notes section of each slide.

+
Relevant digital technologies

Students may wish to use the internet to explore real-life examples of data sets used in a variety of settings.

+
Possible extensions

This activity could usefully be incorporated into a more substantial statistical project or data-based problem-solving activity.
