Q:

# How do you make a pie chart?

A:

To make a pie chart, organize the data as fractions of the whole. Multiply each fraction by 360 degrees, which is the number of degrees in a circle, and assign each multiplied fraction a portion of the pie chart.

1. Collect and organize the data

The entire sum of data is 100 percent of the result, so whether you have 50 results or 5,000 makes no difference. List each possible response as a fraction of that 100 percent by dividing the given response by the total number of responses. For example, if there are a total of 650 responses and 95 of them are "b," then divide 95 by 650 to get the fraction, or percentage, of response "b."

2. Multiply each fraction by 360 degrees

Multiply the fraction for each response. Using the above example, the percentage is 14.6. Multiply 360 by .146, and get the answer 52.56. This is the number of degrees this response will use in the pie chart.

3. Use a protractor to mark the number of degrees inside the circle

Mark the appropriate number of degrees inside the circle for each response. Round the numbers as necessary to ensure all the responses together add up to 360 degrees.

4. Color each sector of the pie chart

Assign each response represented on the completed chart a different color or pattern, so they are visually distinct. Color or shade each sector of the pie chart as desired.

5. Label the chart

Label each response in the chart as desired. Label the entire chart describing the data it represents.
