Pupils are asked to draw graphs to represent data and to critique an erroneous interpretation of the data.

Practical details

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

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
