SURVEY METHODOLOGY
Quote:Results are based on telephone interviews with 1,001 adults, 18 and older, conducted May 2-3, 2007. Results are weighted so that the sample demographics match Census Current Population Survey parameters for gender, age, education, race, region, and population density. The overall margin of sampling error is plus or minus 4 percentage points for results based on 1,001 adults and 831 registered voters. Results based on smaller subgroups are subject to larger margins of sampling error. The margin of error is plus/minus 7 percentage points for results based on 422 registered Democrats and Dem. leaners and plus/minus 8 percentage points for results based on 324 registered Republicans and Rep. leaners. In addition to sampling error, the practical difficulties of conducting surveys can also introduce error or bias to poll results.
News: 422 is almost twice as many as 324.
No! The fifth graders said and they were right.
Plus -does anyone not understand what the meaning of margin of error is?
