Methodological results for the UD Center for Political Communication's “National Agenda Poll” are based on telephone interviews conducted Sept. 16-30, 2010, with a random sample of 901 Delaware adults, aged 18 and older. Respondents were selected using random-digit-dial sampling procedures targeting both cell and landline phone extensions. Based on the total sample for the poll, one can say with 95 percent confidence that the maximum margin of sampling error is plus or minus 4.1 percentage points. In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls. Statistical results presented are weighted to correct known demographic discrepancies.
