What students learn in AC9M9ST05
This unit helps students build a clear, usable understanding of Plan and conduct statistical investigations involving the collection and analysis.... The goal is not to memorise one answer pattern. Students should be able to explain the idea, recognise it in a new example and apply it in a short practice or worksheet task.
- Start with the main idea: plan and conduct statistical investigations involving the collection and analysis of different kinds of data; report findings and discuss the strength of evidence to support any conclusions.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- planning and conducting an investigation using questions together with analysis of secondary data set collected from online data bases such as the Australian Bureau of Statistics planning and conducting an investigation relating to consumer spending habits; modelling market research on what teenagers are prepared to spend on technology compared to clothing, with consideration of sample techniques and potential sources of bias
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
