About this Poll
The Monmouth University Poll was sponsored and conducted by the Monmouth University Polling Institute from August 27 to 30, 2015 with a statewide random sample of 405 Iowa voters drawn from a list of registered Republican voters who voted in at least one of the last two state primary elections and indicate they are likely to attend the Republican presidential caucuses in February 2016. This includes 255 contacted by a live interviewer on a landline telephone and 150 contacted by a live interviewer on a cell phone, in English. Monmouth is responsible for all aspects of the survey design, data weighting and analysis. Final sample is weighted for age and gender based on state registration list information on the pool of voters who participate in primary elections. Data collection support provided by Braun Research (field) and Aristotle (voter list). For results based on the total 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.
