What students learn in AC9M8ST02
This unit helps students build a clear, usable understanding of Analyse and report on the distribution of data from primary.... 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: analyse and report on the distribution of data from primary and secondary sources using random and non-random sampling techniques to select and study samples.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- investigating different methods of sampling used to collect data, considering the source and size of samples comparing the sampling methods of simple random, systematic, stratified, quota, clustered or convenience, or judgement, and discussing the reliability of conclusions about the context that could be drawn
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
