Tips and Tricks and Shortcuts for Pie Charts

Pie Chart Tips, Tricks and Shortcuts :

Pie charts are a common type of data visualization used in data interpretation.

Here are some tips and tricks to solve pie chart questions:

• Read the data in the pie chart carefully: If the distribution is given in percent, simply multiply this value to the total amount of data and then divide by 100 to get the actual value.
• Remember that a whole circle contains 360 degrees: In a pie chart, each sector represents a certain percentage of the total data, which can be calculated using the formula: percentage of a data = (given data/total of all data) x 100.
• Calculate the central angle of each sector using the formula: central angle of a data = (given data/total of all data) x 360 degrees.
• Practice solving pie chart questions with solutions and explanations.
