About this Poll
The Monmouth University Poll was sponsored and conducted by the Monmouth University Polling Institute from October 15 to 18, 2016 with a random sample of 403 likely Wisconsin voters. Interviews were conducted by a live caller in English, including 353 drawn from a list of registered voters (200 landline / 153 cell phone) and a random digit dial supplement of 50 cell phone interviews. Monmouth is responsible for all aspects of the survey design, data weighting and analysis. The final sample is weighted for age, gender, race and voting history based on voter list and U.S. Census information. Data collection support provided by Braun Research (field), Aristotle (voter list sample), and SSI (RDD sample). For results based on this sample, one can say with 95% confidence that the error attributable to sampling has a maximum margin of plus or minus 4.9 percentage points (unadjusted for sample design). Sampling error can be larger for sub-groups (see table below). In addition to sampling error, one should bear in mind that question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of opinion polls.
