To interpret pie charts at GCSE students are taught to use equivalent ratios by identifying a common frequency and angle from the pie chart. As learning progresses they are challenged to compare sets of data by finding the frequencies from various pie charts.
Differentiated Learning Objectives
- All students should be able to recognise the limitations of representing data using pie charts.
- Most students should be able to calculate frequencies from a pie chart when given the sample size.
- Some students should be able to compare data distributions by comparing frequencies found from pie charts
