Measuring Public Opinion

Section 2Slide3

Measuring Public OpinionIn the American political system, information about public opinion is critically important.Elections, interest groups, the media, and personal contacts with the public all provide a means through which the measurement of public opinion can take place.Slide4

ElectionsElection results are often taken to be an indicator of public opinionA mandate refers to the instructions or commands a constituency gives to its elected officials.Election results to not match public opinion exactly so can not be taken as absolute.Slide5

Interest GroupsInterest groups are private organizations whose members share certain views and objectives and work to shape public policies.They are the means by which public opinion is made known.Interest groups don’t necessarily represent all of the people, however.Slide6

The MediaThe media are also a gauge of public opinion.Are both “mirrors” and “molders” of public opinion.Can sometimes be only a mirror of a vocal minority.Slide7

Personal ContactsPublic officials often meet with constituents (those whom they represent) to understand the public’s mind on issues.Some public officials are better at gauging public opinion through these contacts than others.Slide8

Public Opinion PollsPublic opinion polls are devices that attempt to collect information by asking people questions.Straw votes – asking the same question of a large group of people.Not very accurateScientific polling – scientific based statistical analysis of multiple respondents from a truly random sampling of citizens.Slide9

The Polling ProcessScientific polling is extremely complex, Pollsters must1 Define the universe to be surveyed

A universe is a term that means the whole population that the poll aims to measure

2 Construct a sample

A representative slice of the total universe

3 Prepare valid questions

4 Select and control how the poll will be taken

5 Analyze and report their findings to the public.Slide10

Evaluating PollsMajor national polls are fairly reliableRegional surveys tend to be fairly accurate too.

Pollsters have difficulty measuring intensity and stability of public opinion.

Pollsters may shape results if they are not purely objective

Polls are the most useful tools for measuring public opinion.Slide11

Limits on the Impact of PollsPublic opinion is a major force behind political policy but is not the only factor.Governmental structure is not designed to completely reflect public opinion.Civil rights protect minority interests.Civic virtue?
