Masterpiece 2
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 variability in the data.
