Caller ID
The Iowa Emerson College poll was conducted October 19-21, 2020. The sample consisted of likely Democratic, Republican, and Independent voters, n=435, with a Credibility Interval (CI) similar to a poll’s margin of error (MOE) of +/- 5.7 percentage points. The data sets were weighted by gender, age, education, race and region based on 2016 voter turnout modeling. It is important to remember that subsets based on gender, age, party breakdown, ethnicity, and region carry with them higher margins of error, as the sample size is reduced. Data was collected using an Interactive Voice Response (IVR) system of landlines (n=41), SMS-to-web texts (n=331), and an online panel provided by MTurk (n=62).
