# Checking understanding of pie charts

I can construct and interpret pie charts.

## Lesson details

### Key learning points

- Certain data is suitable for a pie chart.
- The shape of the chart can be estimated from the data.
- For larger data sets, technology can make constructing charts quicker.

### Common misconception

A bigger sector on one pie chart compared to another means a larger frequency.

Pie charts show proportion, but tell nothing about frequency. The total frequency of one pie chart could be significantly larger or smaller than the other pie chart.

### Keywords

Sector - A sector is the region formed between two radii and their connecting arc.

Pie chart - A pie chart (pie graph) is a circular graph where sectors represent different groups proportionally.
