Explain Pie Charts ?

If the frequencies are written as percentages, they can be easily compared using a pie chart. The following is an example of a pie chart using the data from the previous two examples:

Step 1: Convert each frequency to a percentage, by dividing the frequency of the events by the total number of events.
• The total number of events is 14.
• The frequency of {17} is 4.
(4+14) 4/14 = 2/7 = 0.2857 = 28.57%
• The frequency of {22} is 3.
(3+14) = 3/14 = 0.2143 = 21.43%
• The frequency of {14 and 15} is 2.
(2+14) = 2/14 = 1/7 = 0.1429 = 14.29 %
• The frequency of {12, 8, and 9} is 1.
(1+14) = 1/14 = 0.0714 = 7.14%
