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

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

- 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.

- 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.

- 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
