The accompanying comparative bar chart is from the report “More and More Teens on Cell Phones”

(Pew Research Center, www.pewresearch.org, August 19, 2009).

Suppose that you plan to include this graph in an article that you are writing for your school newspaper. Write a few paragraphs that could accompany the graph. Be sure to address what the graph reveals about how teen cell phone ownership is related to age and how it has changed over time.
