The National Agenda Opinion Project research was funded by the University of Delaware's Center for Political Communication (CPC) with support from the College of Arts and Sciences. The study was supervised by the CPC's Research Director, Paul Brewer, a professor in the Departments of Communication and Political Science & International Relations.
The study was fielded by Abt Associates and obtained telephone interviews with a representative sample of 995 adults living in Delaware, including 908 registered voters. A total of 348 respondents were interviewed on a landline telephone and 647 were interviewed on a cell phone. Interviewing was conducted from September 11-17, 2018 in English. Samples were drawn from both landline and cell phone random digit dialed (RDD) frames and a list of Delaware registered voters. Both the landline and cell phone RDD samples were provided by Survey Sampling International.
Statistical results are weighted to match the population parameters of the adult population in Delaware.
The margin of sampling error for the sample of registered voters is ± 3.7 percentage points. Overall, the response rate (AAPOR RR3) was 14.4% for the landline RDD sample, 3.6% for the cell RDD sample, 5.8% for landline numbers from the RV sample and 6.7% for cell numbers from the RV sample.
