S4-2: Evaluate statements made by others about the findings of statistical investigations and probability activities.
This means students will critically evaluate the strength of an argument proposed by others that is supported by statistical information. At Level Four students should consider features of the statistical investigation of others in weighing the strength of the findings. These features include the appropriateness of sampling methods (for example number, representativeness), quality of the data collection (for example questions asked, accuracy of measurement, fairness of the experiment), data analysis (technology use, choice of displays) and the extent to which claims made are supported by the evidence.

- Uses the statistical enquiry cycle to plan and conduct investigations
- Identifies broad area to explore using the statistical enquiry cycle
- Poses investigative questions about summary and relationship situations
- Makes predictions/assertions about what they expect to find out
- Plans300
Students will:
- estimate the energy change of a system
- calculate the amount of energy converted by different activities
- use rates to determine inputs and/or outputs.
Students should discover that:
- energy transfer is proportional to work (the more force x distance, the more energy)
- different forms of energy300
- Identify an area of interest to investigate.
- Find data displays including graphs, tables, and non-traditional data representations, that can inform the investigation e.g. from websites and other sources.
- Explore the information behind the data displays to make sense of the data and use it to explore300
