Methodology

Interviewing for The Roanoke College Poll was conducted by The Institute for Policy and Opinion Research at Roanoke College in Salem, Va., between July 8 and July 14, 2013. A total of 525 registered voters in Virginia were interviewed. The sample included both land lines and cell phones and was created so that all cell phone and residential telephone numbers, including unlisted numbers, had a known chance of inclusion. Cell phones constituted 27 percent of the completed interviews.

Questions answered by the entire sample of 525 registered voters are subject to a sampling error of plus or minus approximately 4.3 percent at the 95 percent level of confidence. This means that in 95 out of 100 samples like the one used here, the results obtained should be no more than 4.3 percentage points above or below the figure that would be obtained by interviewing all Virginia registered voters who have a home telephone or a cell phone. Where the results of subgroups are reported, the sampling error is higher.

Quotas were used to ensure that different regions of the Commonwealth were proportionately represented. The data were statistically weighted for gender, race and age.
