Students choose representations by variable type and question, calculate or organise data transparently and interpret patterns while distinguishing what a model or graph shows from what it cannot establish.
A representation is appropriate when it preserves the evidence and makes the relevant relationship easier to inspect.
Use labels, units and consistent scales. Calculated values such as means should be traceable to raw data.
Graphs reveal relationships but do not alone prove cause. Link conclusions to the method and scope.
Learning routine: Observe → Model → Investigate → Analyse → Explain → Evaluate
Success looks like
- Identify system components
- Explain relationships with a model
- Use evidence from a fair method
- Apply to a new context
- Evaluate limits and further questions
