What students learn in AC9M10ST04
This unit helps students build a clear, usable understanding of Construct two-way tables and discuss possible relationship between categorical variables. 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: construct two-way tables and discuss possible relationship between categorical variables.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- using two-way tables to investigate and comparing the survey responses to questions involving five-point Likert scale against 2 different categories of respondents; for example, junior compared to senior students’ responses to a survey question recording data in two-way tables and using percentages and proportions to identify patterns and associations in the data
- 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: construct two-way tables and discuss possible relationship between categorical variables
- E1: using two-way tables to investigate and comparing the survey responses to questions involving five-point Likert scale against 2 different categories of respondents; for example, junior compared to senior students’ responses to a survey question
- E2: recording data in two-way tables and using percentages and proportions to identify patterns and associations in the data
- E3: conducting a litter survey around the school, considering the relationship between different categorical variables such as the day of the week as canteen specials might lead to different types of litter or the weather due to hot days leading to more ice blocks and cold drinks being sold
