Teacher guidance
Check that pupils understand the context before they begin, for example, issue the task and ask questions such as the following:
- What is the purpose of this survey?
- What was the survey question?
- Why would they want to ask this question?
- How many people responded?
Pupils can tackle this task in different ways, but they might be expected to:
- solve simple problems involving ratio and direct proportion
- understand and use the mean of discrete data
- group data into equal class intervals where appropriate
- represent collected data in frequency diagrams
- interpret graphs and diagrams and draw conclusions
