HOW THE POLL WAS CONDUCTED

Monday's Star Tribune Minnesota Poll findings were based on 804 land-line and 402 cell phone interviews conducted Oct. 18-21 with a representative sample of Minnesota adults. Interviews were conducted under the direction of Princeton Survey Research Associates International.

Results of a poll based on 1,206 interviews will vary by no more than 3.6 percentage points, plus or minus, from the overall population 95 times out of 100.

The self-identified party affiliation of the random sample is 33 percent Democrat, 27 percent Republican and 34 percent independent. The remaining 6 percent said they were members of another party, no party or declined to answer.

Sampling error does not take into account other sources of variation inherent in public opinion surveys, such as nonresponse, question wording, context effects or news events. Readers can e-mail questions to djmcgrath@startribune.com.
