Pie charts

Question	Answer
Pie charts	People use pie charts in a more visual way rather than writing it in a small table.
Making Pie charts	1) You should have a small table with your results in it. You have to add all the results together to get an overall amount. 2) You then have to get the separate result and divide that by the overall amount and times that by 360. The number you are left with is the angle for the pie chart. 3) You will need to draw a circle for the pie chart and using a protractor you will need to add all of the angles in. Once you have that, label the sections from the table.
Example	An example would be like having 12 children who are 10-14 years old and 6 people who are 15-19 year olds and 22 people who are 20-24 years old. 1) First of all you have to add all of the frequencies together (22 + 6 +12 = 40) 2) Then you have to divide each separate number by the overall number and times it by 360. (22/40 x 360 = 198) etc.
