"Methodology"
"The most recent survey by Fairleigh Dickinson University’s PublicMind
was conducted by telephone from October 1-5, 2015 using a randomly
selected sample of 824 registered voters nationwide. One can be 95
percent confident that the error attributable to sampling has a range of
+/- 4.1 percentage points, including the design effect. The margin of
error for subgroups is larger [eg, Republican, Democrat, Independent] and varies by the size of that subgroup.
Survey results are also subject to non-sampling error. This kind of
error, which cannot be measured, arises from a number of factors
including, but not limited to, non-response (eligible individuals
refusing to be interviewed), question wording, the order in which
questions are asked, and variations among interviewers.
Interviews were conducted by SSRS of Media, Pennsylvania, with
professionally trained interviewers using a CATI (Computer Assisted
Telephone Interviewing) system. Random selection is achieved by
computerized random-digit dialing. This technique gives every person
with a landline or cellular phone number (including those with unlisted
numbers) an equal chance of being selected.
The total combined sample is mathematically weighted to match known
demographics of age, sex, race, and education. 452 interviews were
conducted on landlines and 372 were conducted on cellular telephones.
The sample was purchased from Marketing Systems Group and the research was funded by Fairleigh Dickinson University."
