Please respond to the following research methods questions:
1. When polling experts list the results of their surveys of the public’s attitudes, why do they list plus or minus percentage points (for example, “results accurate to +/- 2%”) ?
2. Is there an important concern about how public surveys are worded? For example, are the following questions seeking the same research information? Why or why not?
“Is the president is policy on the prevention of terrorism effective?”
“Are you satisfied with the present’s policy on the prevention of terrorism?”
