How to solve Pie Charts Quickly

How To Solve Pie Chart Questions:

Pie charts are a useful way to organize data in order to see the size of components relative to the whole, and are particularly good at showing percentage or proportional data.

Concept of Pie Chart

• Reading a pie chart is as easy as figuring out which slice of an actual pie is the biggest.
• Usually, you have several bits of data, and each is pictured on the pie chart as a pie slice. You will see that some data have larger slices than others.
• So you can easily decipher which data is more important to your audience than others.

To solve pie chart questions, follow these steps:

1. Categorize the data and calculate the total.
2. Divide the categories and convert them into percentages.
3. Calculate the degrees of each category by multiplying the percentage by 360 and dividing by 100.
4. Draw a circle of an appropriate radius and a vertical radius inside the circle.
5. Choose the largest central angle and construct a sector of a central angle whose one radius coincides with the radius drawn in step 4, and the other radius is in the clockwise direction to the vertical radius.
6. Calculate the central angle subtended by each category and draw the corresponding sector.
7. Label each sector of the pie chart.
