About this Poll

Poll interviews were conducted by telephone Oct. 3-14, 2011 by students in the College of Mass Communication at Middle Tennessee State University. Students interviewed 640 people age 18 or older chosen at random from the state population. The poll has an estimated error margin of ± 4 percentage points at the 95 percent level of confidence. Theoretically, this means that a sample of this size should produce a statistical portrait of the population within 4 percentage points 95 out of 100 times. Other factors, such as question wording, also affect the outcome of a survey. Error margins are greater for sample subgroups.
