About this Poll
The survey findings presented in this release are based on the results of interviews
conducted August 17 - 24, 2015. The interviews were conducted at the Center for Opinion
Research at Franklin & Marshall College under the direction of the poll’s Director Dr. G. Terry
Madonna, Head Methodologist Berwood Yost, and Project Manager Jacqueline Redman. The
data included in this release represent the responses of 605 Pennsylvania registered voters,
including 298 Democrats, 228 Republicans, and 79 Independents. The sample of registered
voters was obtained from Labels & Lists. Survey results were weighted (gender, region and party
registration) using an iterative weighting algorithm to reflect the known distribution of those
characteristics as reported by the Pennsylvania Department of State.
The sample error for this survey is +/- 3.9 percentage points when the design effects from
weighting are considered. In addition to sampling error, this poll is also subject to other sources
of non-sampling error. Generally speaking, two sources of error concern researchers most. Nonresponse
bias is created when selected participants either choose not to participate in the survey
or are unavailable for interviewing. Response errors are the product of the question and answer
process. Surveys that rely on self-reported behaviors and attitudes are susceptible to biases
related to the way respondents process and respond to survey questions.
