In KS3 Maths, you'll dive into data handling, and that involves showing information with graphs, tables, or charts. This quiz zooms in on one of these – the pie chart.
A pie chart is like a visual guide to see how data is spread across categories. Each category gets a 'slice' of the pie, and the bigger the 'slice', the more important that category is.

Imagine 100 people naming their favourite film genre. If 50 say comedy and only 5 say romance, the comedy slice is like half the pie, and romance is just one-tenth. Now, the tricky part is turning these fractions into degrees.
Remember, a whole circle has 360o, so 1% is 3.6o. In our example, comedy takes 180o, and romance is 36o. Simple once you get the hang of it! Give this quiz a go to see how well you get pie charts.
