About this Poll
The survey findings presented in this release are based on the results of interviews conducted October 20-25, 2009. 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 Jennifer Harding. The data included in this release represent the responses of 616 adult residents of Pennsylvania, including 529 registered adults. Telephone numbers for the survey were generated using random digit dialing, and respondents were randomly selected from within each household. Survey results were weighted (age, education, race, region, and gender) using an iterative weighting algorithm.

The sample error for this survey is +/- 3.9 percentage points. The sample error for registered adults is +/- 4.3 percentage points. 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. Non-response bias is created when selected participants either choose not to participate in the survey or are unavailable
