Why would you use a circle graph?

• when you have continuous data

• to compare the frequency of the data

• when the data is too large for any other graph

• to show how the total data is divided into parts

Why would you use a histogram?

• good for continuous data and when you want to see intervals

• when organizing numerical data

• useful to compare how things change over time

• when you want to show the total divided into parts
