Results for this survey are based on telephone interviews conducted under the direction of Schulman, Ronca, & Bucuvalas, Inc. among a nationwide sample of 1,399 adults, 18 years of age or older, from November 20-26, 2007. For results based on the total sample, one can say with 95% confidence that the error attributable to sampling is plus or minus 3 percentage points. For results based on Form 1 (N=724) or Form 2 (N=675) only, the error attributable to sampling is plus or minus 4 percentage points.

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.
