A typical pie chart shows information in a circle with divisions, where relationships between facts can be seen easily.
In this example, the slices of the pie chart show the results of a survey of preferences for activities. Each activity is shown as a larger or smaller piece of the pie according to the number of people who chose that activity as their favorite way to spend time. A pie chart shows quickly the relative importance between different included factors. For example, the level of popularity of activities surveyed for this chart are quite obvious. A pie chart is also a very straightforward way to convey factual information. It would take a long time to explain in words or text what this pie chart shows at a glance.
Take another look at the pie chart and see if you can answer the following questions.
- What is the most popular activity of those surveyed?
- What is the least popular activity of those surveyed?
- Which activities are similar in popularity among those surveyed?
- Which activity is twice as popular as one or more other activities?
