plan and conduct statistical investigations involving samples of a population; use ethical and fair methods to make inferences about the population and report findings, acknowledging uncertainty

What students learn in AC9M8ST04

This unit helps students build a clear, usable understanding of Plan and conduct statistical investigations involving samples of a population.... 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 samples of a population; use ethical and fair methods to make inferences about the population and report findings, acknowledging uncertainty.
  • Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
  • using data such as electricity consumption to draw conclusions about the impacts of events, such as pandemics, on households or business identifying situations where the collection of data from a sample is necessary due to efficiency, cost or restricted time for collection of data, and sufficiently reliable for making inferences about a population
  • Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
