Pupils are asked to draw graphs to represent data and to critique an erroneous interpretation of the data.
- National Curriculum levels 4 to 5
- 30 minutes to 1 hour
- Ruler, pencil and graph paper
Key Processes involved
- Choose a way of representing discrete data using a chart or graph and an appropriate method for evaluating a conclusion about the data
- Compare two proportions and make deductions
- Interpreting and evaluating
- Engage with someone else's reasoning and identify errors
- Communicating and reflecting
- Communicate their findings clearly
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
