Use a Graph to Answer Questions

Choose a question to investigate as a class or in small groups. Write the question you chose on a sheet of paper. Make a prediction about what you think you will discover. Then write your prediction below the question. Also write one or two sentences to explain your prediction. Click on the numbers next to the question you selected to view graphs that might help you answer your question. Click here for more graphs.
