• Pie charts are graphs that show information about a situation in the shape of a circle.
• For making the pie chart, the unitary method is used to turn the values of the graph into angles.
• In a pie graph, the pie represents the whole problem with numbers, and the slices represent the parts of the circle that can be measured.
• For a statistical look at the problem, pie charts are used.
• When you add up all of the angles made by the sectors in a pie chart, you get 360°.

Steps for creating a pie chart in general:

• Here are some general steps that should be taken to make the pie chart for each question.
• Write down all the information in the question as a table with the category and the information value.
• Find the sum of all the numbers.
• Next, figure out how much each sector makes up.
• This is found by dividing the value of each sector by the total number of data points and then multiplying that number by 100.
• Now, you need to figure out how many degrees each slice of the pie chart represents. To do this, divide the given data by the total data and then multiply that number by 360°.
• The last step in making a pie chart is to use a protractor to draw a circle and measure each angle from a central point to show how much of each category is in that circle.
• Now, label and color each part of the circle with the data that goes with it.

How to Use Pie Charts

• When analyzing statistics, pie charts are used for things like:
• These charts are used to show financial information about a business, such as its annual sales, profits and losses, assets, and debts.
• Pie charts can also be used to show data about groups of things.

Disadvantages of Pie Charts:

• Even though pie charts are used in many different situations and help statistically analyze data, there are still some problems with using them. These are:
• When there is a lot of information to look at, you can’t use pie charts.
• Using pie charts to look at and compare data is harder and takes more time than other methods.
• If the data we’re looking at is hard to understand, the pie chart is even harder to understand.
