• Solve a problem by representing, extracting and interpreting data in tables, graphs, charts and diagrams.
  • Solve problems by representing data in a bar chart and line graph.


  • Given a problem that can be addressed by statistical methods, suggest possible answers.
  • Decide which data would be relevant to an enquiry and possible sources.
  • Plan how to collect and organise small sets of data; design a data collection sheet or questionnaire to use in a simple survey; construct frequency tables for discrete data, grouped where appropriate in equal class intervals.
  • Collect small sets of data from surveys and experiments, as planned.
  • Construct, on paper and using ICT, graphs and diagrams to represent data, including:
    • bar-line graphs;
    • frequency diagrams for grouped discrete data;
    • use ICT to generate pie charts.
  • Interpret diagrams and graphs (including pie charts), and draw simple conclusions based on the shape of graphs.
  • Solve word problems and investigate in a range of contexts: handling data.


  • Decide the degree of accuracy needed for the data.
  • Plan how to collect the data, including sample size; construct frequency tables with given equal class intervals for sets of continuous data.
  • Construct on paper and using ICT:
    • pie charts for categorical data;
    • simple line graphs for time series.
