WASHINGTON —

The Associated Press-GfK Poll on the health care bill was conducted by GfK Roper Public Affairs & Corporate Communications from Jan. 5-10, 2011. It is based on landline and cell phone telephone interviews with a nationally representative random sample of 1,001 adults. Interviews were conducted with 701 respondents on landline telephones and 300 on cellular phones.

Digits in the phone numbers dialed were generated randomly to reach households with unlisted and listed landline and cell phone numbers.

Interviews were conducted in both English and Spanish.

As is done routinely in surveys, results were weighted, or adjusted, to ensure that responses accurately reflect the population's makeup by factors such as age, sex, education, and race. In addition, the weighting took into account patterns of phone use - landline only, cell only and both types - by region.

No more than one time in 20 should chance variations in the sample cause the results to vary by more than plus or minus 4.2 percentage points from the answers that would be obtained if all adults in the U.S. were polled.

There are other sources of potential error in polls, including the wording and order of questions.

The questions and results are available at http://www.ap-gfkpoll.com.
