A pie chart can show collected data in sectors. Each sector can be labelled, or can be colour coded with a key. When drawing a pie chart, a protractor will be used to draw the angles accurately.

The pie chart below shows the heights (in \(cm\)) of 30 pupils in a class. The biggest slice of the pie chart contains the most people: \( 151 - 160cm\). The angle of this sector is \(36^{\circ}\).

Today, we update one of our favorite charts, which looks at how orders route ... and how orders are handed by brokers, means each pie actually works quite differently to the others.
