Document Summary
1896 - democrats // republicans; william jennings bryan. Public opinion poll - cannot contact everyone, so representative sample is used. Random selection - characteristics of normal distribution; normal curve/bell curve/gaussim distribution. Result from representative sample is 3% from the actual percentage. Margin of error, smaller sample - larger margin. Elections - general and primary (for who will compete in the general election) In-person surveys, interviewed for an hour at home but problem is it takes a lot of effort. 1936 literary gazette, election between fdr and landon. Conduct this survey using the telephone, find out that landon wins by a landslide a week before the election, (60-35%). The survey did not have a representative sample because the poor people did not have telephones. Skewed in favor of the rich, ending up with these results. Yes, they are younger, richer and tend to lean on the democratic party. If they are excluded from the survey, the results are bias.
