Sam Dolnick, The Obesity Hunger Paradox, New York Times, March 12 2010, http://www.nytimes.com/2010/03/14/nyregion/14hunger.html?scp=1&sq=statistical%20survey&st=cse
1) This particular study was conducted by Gallup.
2) The research was sponsored by the Food Research and Action Center, which is a group that works to prevent hunger.
3) I don't believe the center has an interest in finding a particular result. It merely wants to use those results to correct a problem, if one is found, and also to determine the location of the problem. It is possible though that they want to use the results in order to persuade local governments or Federal governments to fix the hunger issues in the United States, especially in those areas it finds to be the worst off.
4) Not much information on methodology is included. Gallup took a sample of more than 530,000 people from across the U.S. but how the sample was chosen it does not say. Most likely the sample was chosen randomly but this is not certain.
5) The results are communicated in a clear and informative way. They are written in a small paragraph and show that at the state level the south is the hungriest. It then goes on to list the percentages for these states. It also reports national statistics for hunger from 2008-2010. The counties are not listed, and only a few are mentioned. The point is carried across though that the Bronx is the hungriest area and by state the south is hungriest. Nationally it showed that food hardship has dropped since 2008.
6) There are no graphs to show the statistics reported in this article.
