Resources for teaching statistics: Classroom Activities, Key Resources

Students use the PPDAC cycle to investigate whether a person’s armspan is equal to their height using their own measurements or CensusAtSchool data.
This activity explores the following key ideas:

  • Carrying out a statistical investigation following the full PPDAC cycle
  • Posing a statistical question
  • Describing the data set in terms of shape, spread and middle range
  • Finding a relationship between variables
  • Comparing subsets of data
  • Supporting claims with evidence

They are also encouraged to consider the reasons for variabilility in the data.
