About this Poll
The results of this poll are based on 1,067 interviews of
registered Virginia voters, including 559 on landline and
508 on cell phone, conducted Sept. 29 – Oct. 8, 2015.
Percentages may not equal 100 due to rounding. The
margin of error for the whole survey is +/- 3.2% at the
95% level of confidence. All error margins have been
adjusted to account for the survey’s design effect, which
is 1.15 in this survey. The design effect is a factor
representing the survey’s deviation from a simple
random sample, and takes into account decreases in
precision due to sample design and weighting
procedures. In addition to sampling error, the other
potential sources of error include non-response, question
wording, and interviewer error. The response rate
(AAPOR RRI Standard Definition) for the survey was
24%. Five callbacks were employed in the fielding
process. Live calling was conducted by trained
interviewers at the Wason Center for Public Policy
Survey Research Lab at Christopher Newport
University. The data reported here are weighted using an
iterative weighting process on sex, age, race and region
of residence to reflect as closely as possible the
demographic composition of registered voters in
Virginia. The survey was designed by Dr. Quentin Kidd
of the Wason Center for Public Policy at Christopher
Newport University.
