AP Poll method, questions and results

The Associated Press-Ipsos poll on the Transportation Security Administration and air travel was conducted December 17-19, 2007, and is based on telephone interviews with a nationally representative random sample of 1,004 adults from all states.

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

No more than one time in 20 should chance variations in the sample cause the results to vary by more than plus or minus 3.1 percentage points from the answers that would be obtained if all people in the U.S. were polled.

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