What students learn in AC9M10M04
This unit helps students build a clear, usable understanding of The impact of measurement errors on the accuracy of results.... 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: identify the impact of measurement errors on the accuracy of results in practical contexts.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- describing settings where measurement errors may impact research results and how measurement data impacted by error can result in biased findings analysing instruments and methods for measuring in investigations and modelling activities
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
Curriculum coverage and elaborations
The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning but may not appear in the initial eight-question activity.
- Content description: identify the impact of measurement errors on the accuracy of results in practical contexts
- E1: describing settings where measurement errors may impact research results and how measurement data impacted by error can result in biased findings
- E2: analysing instruments and methods for measuring in investigations and modelling activities
- E3: determining the impact that compounding errors have on financial calculations; for example, considering the effect of truncation on money amounts for large scale customer populations
- E4: investigating the impact of measurement errors in the perception and control systems of autonomous vehicles, such as measurement errors due to sensor limitations
- E5: investigating scientific measuring techniques, including dating methods and genetic sequencing, applied to First Peoples of Australia and their artefacts, and the social impact of measurement errors
