Method for AP-Yahoo poll

The AP-Yahoo News Poll is a unique study that is tracking the moods and opinions of a group of people throughout the presidential election campaign.
The ninth wave of this study included interviews of 1,753 adults between October 17-27 originally interviewed in November or early December of 2007.
The extensive national survey is being conducted by Knowledge Networks of Menlo Park, California, under the direction and supervision of The Associated Press' polling unit.
Interviews were conducted online. The original sample was drawn from a panel of respondents Knowledge Networks recruited through random sampling of landline telephone households with listed and unlisted numbers. The company provides Web access to panel recruits who don't already have it. With a probability basis and coverage of people who otherwise couldn't access the Internet, the Knowledge Networks online surveys are nationally representative.
Results were weighted, or adjusted, to reflect the adult population by demographic factors such as age, sex, region, race, and education.
No more than one time in 20 should chance variations in the sample cause results to vary more than plus or minus 2.3 percentage points from the answers that would have been obtained if all adults in the U.S. were surveyed.
There are other, potentially greater, sources of variability in surveys, including the wording and order of the questions.
