POLS 233 Final Exam Review Flashcards
(123 cards)
despite their flaws, public opinion polls remain the best method available for understanding what the public thinks. why?
-no selection bias
-margin of error (sampling error)
what other ways do we have for understanding public opinion and what are the limitations of those methods?
convenience sample
limitations
-selection bias
-no way of evaluating how representative a sample is
population
full set of individuals who could potentially take part in the research
sample
a subset of the population
what is the difference between a probability and a non-probability sample?
in probability sampling, individuals are selected randomly, whereas, in non-probability sampling, the selection is based on accessibility or the researcher’s judgment.
why is probability sampling preferred?
-no selection bias (researchers do not choose who to interview)
-we can evaluate the representatives of the sample (margin of error)
why is it possible to get a reasonably close approximation of public opinion with a survey of 800-1000 respondents?
the larger the sample, the smaller the error
how do polling results change as you move from adults to registered voters to likely voters?
likely voters
-prior turnout
-knowledge about voting process
-correlates of voter turnout
how do pollsters determine likely voters?
most pollsters use a combination of questions that measure intention to vote, interest in the campaign, and past voting behavior. different pollsters use different sets of questions to help identify likely voters.
conventional wisdom is that the polls have gotten less accurate over time. is this true>
yes, but they were historically accurate in 2022
how do we evaluate the accuracy of polling
the best way to measure the accuracy of a poll is to look a its absolute error-the difference between a poll margin and the actual margin of the election (between the top two finishers in the election, not the poll)
weighted average error takes into account the number of polls done by a polling organization
polls are wrong but wrong in ways that make their predictions correct
pack
what does the margin of error tell us about a poll result? What does it tell us?
the margin of error describes how close we can reasonably expect a survey result to fall relative to the true population value. the margin of error that pollsters customarily report describes the amount of variability we can expect and indicate candidates’ level of support
explaining what happens when polling is wrong therefore is more like investigating someone’s overall health than it is like investigating a murder
pack
polls’ true utility is
in telling us how close the race is
how do we know what hte public wants?
-elections
-callas, letters, social media psots
-sientific opinipon pollling!Representing population preferences with a probability-based sample
* Random Samples versus Convenience Samples
Why is public opinion polling better than other forms of know what the public thinks?
- No selection bias
- Margin of error! (sampling error
consequneces of public opinion polling
Nonresponse!
Question wording (Measurement Error)
Social Desirability Bias
Weighted average error
takes into account the number of polls done by a polling organization.
Voting Could Be the Problem with Democracy (Reiter)
Random selection of representatives?
Allows the average person to participate Reduces campaign and money influence in elections (policy)
Deliberative polling
Direct democracy can force governments to better represent the people - but it doesn’t always work out (Stokes)
Referendums & Initiatives
Influence of special interests & money
Use by autocrats (Putin) Potential depends on context!
Three Stages of Ignorance (Borowitz)
- Ridicule: Dumb politicians pretend to be smart, ignorance not socially accepted
- Acceptance: Politicians pretend to be “regular” or “average”
- Celebration: Smart politicians play dumb
The flow model of political system presented by
David Easton in “An Approach to the Analysis of Political System” (in World Politics,
Classic Liberal Democratic Theory
Democracy as enlightening (and rooted in the enlightenment), committed to individualism, liberty, the rule of law (and equality before the law), a market economy, and limits on government power
- Given the opportunity to self-govern, citizens:
- Engage in politics (political participation)
- Learn about politics and the political system, becoming informed about candidates, political parties, and political issues
- Be tolerant of opposing points of view and accept democratic outcomes even when (especially when) they disagree with the outcome
