What is a Pie Chart?
A Pie Chart is a type of graph that displays data in a circular graph. The pieces of the graph are proportional to the fraction of the whole in each category. In other words, each slice of the pie is relative to the size of that category in the group as a whole. The entire “pie” represents 100 percent of a whole, while the pie “slices” represent portions of the whole.
How to Make a Pie Chart
In order to make a pie chart, you must have a list of categorical variables (descriptions of your categories) as well as numeric variables. In the above graph, percentages are the numerical variables and the type of trash are the categorical variables.
Pie charts can be tricky to draw by hand, especially with tricky percentages; the whole of the pie is 360 degrees, so drawing 13.9 percent or 56 percent presents a challenge. It isn’t really necessary with the wide variety of computer programs that can make pie charts for you. Two of the most popular programs for making charts in elementary statistics or AP statistics classes are Microsoft Excel and IBM SPSS Statistics:

Note: When you make a pie chart, you must make sure that your categories don’t overlap, otherwise you’ll have a meaningless chart. For example, if you have a chart of what breeds of dog U.S. pet owners own, you can’t put a husky-German shepherd mix in two categories, otherwise it will create larger pieces of the “pie” for those categories.

Example question: Make a pie chart in Excel that represents what percentage of people in a certain town own certain types of pets:
Dogs (1110 people),
Cats (987 people),
Rodents (312 people),
Reptiles (97 people),
Fish (398 people).
Step 1: Type your data into an Excel worksheet. Type your categories in one column and your numbers into a second column. For this example problem, the categories would be the type of pets, so type those into column A. Type the numbers associated with each category into column B. Do not leave blank rows or columns when typing in the data.

In most cases with simple pie charts like the one in this sample problem, the first selection (2D) will work fine. Once you have clicked the chart icon, Excel will insert the pie chart into your worksheet.

Tip: If you made a mistake in your entries, you don’t have to redo the entire chart; type your correction in the original data that you entered and Excel will automatically make the correction to the chart.
