You must respond to the following questions.

This infographic was published in a NY Times article.

• The article’s print version states “Experts disagree almost as much as non-experts.” Find evidence of this in the graph. (Hint: Examine the ratings of foods on the y = x line.)
• Describe the cluster of foods on y = x (27 percent of foods); the cluster in y > x region (44 percent); the cluster in y < x region (29 percent). Hypothesize what these the foods in a cluster and their ratings have in common.
• How were the foods picked for the surveys? Based on what it says in the article, do you think this would give a broad sample of foods that are commonly eaten? (Hint: Why is there a gap in the middle of the graph?)
• How was the data collected? Based on what it says in the article, do you think this would give a reasonable sample of the general public and nutritionists? If not, why not? What could they have done differently?
• Why do steak and hamburgers rate so different? How about American and Cheddar cheese?
