Description:
For example, Pew Research Center conducted a survey with the following question: "As you may know, by 2014 nearly all Americans will be required to have health insurance. People who do not buy insurance will pay a penalty while people who cannot afford it will receive financial help from the government. Do you approve or disapprove of this policy?" For each randomly sampled respondent, the statements in brackets were randomized: either they were kept in the order given above, or the two statements were reversed.
