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
