Georgia Newspaper Partnership/Mason-Dixon Poll Methodology

The Georgia Newspaper Partnership poll was conducted by Mason-Dixon Polling & Research, Inc. of Washington, D.C. from July 8 through July 13, 2010.

625 likely voters were polled on general questions and an oversample of 400 Democrats and 400 Republicans was sampled on questions relating specifically to the upcoming primary election. The telephone interviews were randomly selected and distributed across Georgia.

The margin for error is plus or minus 4 percentage points overall and plus or minus 5 percentage points for each party oversample. This means that there is a 95 percent probability that the "true" figure would fall within that range if the entire population were sampled.

The margin for error is higher for any subgroup, such as a regional or gender groupings. Race and age subgroups have considerably higher margins of error and should not be considered statistically valid.
