Creating a Circle Graph

Circle graphs are a great way to display data that relates parts to a whole. Dropin #4 links you to two sites where you can learn how to read and interpret circle graphs. Now let’s learn how to create our own circle graphs!

Visit Constructing Circle Graphs at http://cstl.syr.edu/fipse/TabBar/BldCirc/BUILDCIR.HTM

Look carefully at each step of the example problem to learn how to construct a circle graph. Then complete the activity below!

Now you are ready to create your own circle graph! In addition to paper and pencil, you will need the following tools:

a compass, a calculator, and a protractor.

Use the information you learned in Constructing Circle Graphs to make a circle graph about the types of hiking trails in Acadia National Park (<<http://www.americanparknetwork.com/parkinfo/ac/

walking/trails.html>>).

Begin by making a frequency table of the five types of trails: very easy, easy, moderate, difficult, and strenuous.

Next find the percentage of each type compared to the whole

(the total number of trails). Convert each of these percents to degrees, and then make your graph!

Be sure to give your graph a good title and label each part, then use colored pencils to make your circle graph attractive!
