    Opinion

    CHAPTER 18, SECTION 4

    Essential Question:How is public opinion

    measured?

    Nonscientific MethodsIn order for politicians to know what the public is thinking, methods are used to figure out public opinion.Nonscientific methods of analyzing public opinion

    include using political parties and interest groups, mass media, letters and emails, straw pols, and political websites.

    A straw poll does not use scientific procedures to choose the respondents, rather, it uses people who want to partake in the poll voluntarily. This usually causes a biased sample of the population. Biased

    sample is polling a small group that does not accurately represent the larger population.

    Scientific PollingMost politicians today use scientific polls to measure public opinion. Scientific polling involves three basic steps:

    1. Selecting a sample of the group to be questioned2. Presenting a carefully worded question or questions to the

    individuals in the sample.3. Interpreting the results.

    A sampling error is a measurement of how much the sample results of a scientific poll might differ from the actual number. Usually, the results of a poll will say that the error is only plus or minus 3 percent off.

    Scientific PollingPolling has improved greatly since the 1930s, however it is still far from being completely accurate, and it never will be completely accurate. An election exit poll is a poll taken immediately after voters have exited their polling station. Usually news broadcasters such as Fox News and CNN will conduct exit polls to gain an indication as to how an election has turned out because in some elections the actual results might take days to count.
