How the Minnesota Poll was conducted
March 23, 2015 at 5:07AM
Results of a poll based on 625 interviews will vary by no more than 4.0 percentage points, plus or minus, from the overall population 95 times out of 100. Margins are larger for groups within the sample, such as Democrats and Republicans, and income groups.
The self-identified party affiliation of the respondents is 29 percent Democrats, 26 percent Republicans, 23 percent independents and 22 percent other.
Sampling error does not take into account other sources of variation inherent in public opinion surveys, such as nonresponse, question wording or context effects. In addition, news events may have affected opinions during the period the poll was taken.
