Question 3: (20 Points)
Search the internet for a line, circle, or bar graph that either misrepresents the information being portrayed, is confusing, or doesn’t do a good job representing the information. Copy and paste the graph below. Do not use graphs from other schools or college sites like Khan Academy, but rather find a graph used in a news article, finance article, whitepaper, or other story.
Explain in a well-constructed essay why you chose the graph, what the graph’s shortcomings are, and how you would suggest fixing it. Be sure to cite the graph’s source, title, legend, labels, colors chosen, axis labels, and general layout.
Your essay should be complete and cover each point as outlined above. Be sure to include at least one text citation.
