Statistical Diagrams

Scheme of work: GCSE Foundation: Year 9: Term 1: Statistical Diagrams

Prerequisite Knowledge

  • Solve comparison, sum and difference problems using information presented in a line graph
  • complete, read and interpret information in tables, including timetables.

Success Criteria

  • interpret and construct
  • frequency tables
  • bar charts
  • pie charts
  • pictograms
  • pie charts
  • for categorical data.
  • interpret and construct
  • vertical line charts for ungrouped discrete numerical data
  • tables and line graphs for time series data
  • and know their appropriate use.

Key Concepts

  • Frequency tables must not have overlapping categories.
  • Diagrams must not imply bias (e.g., equal width bar charts0
  • Pictograms need to use suitable symbols to illustrate fractional amounts
  • Students need to spend time interpreting the diagrams as well as creating them.

Common Misconceptions

  • Bar charts are often drawn with unequal-width bars.
  • Students often use nonlinear scales for bar and line graphs.
  • The frequency is often incorrectly taken as the angle when drawing pie charts.
  • Diagrams are often drawn without the correct labels and missing titl
