The poll is based on a random sample of adults, 18 years of age and older. A random sample is one in which everyone in the population has an equal chance of being selected.
We typically report poll results based on registered voters (self identified), rather than all adults, because our polls focus on politics and elections. As we get closer to an election, we report the results based on likely voters.
We use screen questions to determine likely voters. We use different screen questions depending on the election (ie. primary vs general election, presidential vs. off-year election, etc.). In past elections, we have used questions measuring intention to vote, attention to the campaign, past voting behavior, and interest in politics to identify who is likely vote.
Only adults are interviewed because we use the demographic information for weighting purposes. Weighting is a statistical adjustment of the data. Gender, age, education, race, and region are the demographics that are weighted to reflect census information.
We use random digit dial (RDD) sampling. In RDD sampling, phone numbers are randomly generated by a computer. RDD is used to ensure that both listed and unlisted phone numbers have a chance of being included in the sample. We purchase our samples from Survey Sampling in Shelton, Conn.
Typically, the field period for interviewing is four to seven days. We call from 6 to 9 p.m. Monday through Friday with additional hours on Saturday and Sunday.
If there is a no answer, we will "call back" that number. We will call every number where there is a no answer at least three times. We do call cell phones. This is increasingly important as more than a third of the nation is cell only and young people are much more likely than older people to be cell only.
We do interview in Spanish if a respondent prefers to be interviewed in Spanish.
We use live callers, not prerecorded voices. Our interviewer staff is a mix of students and non-students who are professionally trained and closely monitored.
We have 150 Computer Assisted Telephone Interviewing (CATI) stations. Our CATI software is WebCATI from CfMC (Computers for Marketing Corporation).
