Quantitative Methods Questions
The main difference between a pie chart and a donut chart lies in their appearance and the way data is presented.
A pie chart is a circular graph divided into slices, where each slice represents a category or a proportion of a whole. The size of each slice is proportional to the value it represents, allowing for easy comparison between categories. Pie charts are commonly used to display data with a few distinct categories and are effective in showing the relative proportions of each category.
On the other hand, a donut chart is also a circular graph with a hole in the center, creating a ring-like shape. Similar to a pie chart, it represents the proportions of different categories. However, the center hole in a donut chart allows for additional information to be displayed, such as a total value or a secondary category. Donut charts are useful when there is a need to show both the overall distribution of categories and a specific breakdown within a category.
In summary, while both pie charts and donut charts are circular graphs used to represent proportions, the donut chart includes a center hole for additional information, making it more versatile in certain situations.
