Backgrounder: Understanding Public Opinion Polls
Election terms
Suggested time
This lesson should take approximately two class periods of 45-50
minutes each, and one homework assignment. You may want to
provide additional time to allow students to research additional polls.
Procedures
Introduction: Journalists ask questions to get information. Polls do
just that; they ask people questions. Polls have become a very
important tool in elections. Candidates conduct polls to determine
where they stand in the ratings against their opponents. They can also
use them to better understand public opinion so that they can develop
a message that appeals to key constituents or to create support for
their positions. The news media uses polls to support a particular
angle for a story, to report voter opinion to their subscribers or to
simply cover candidate approval ratings. But while modern scientific
polls have become fairly accurate, there are several factors that could
bias, or affect, the accuracy of polls. For example, how the question is
stated, when it is asked, whether it is scientific or unscientific. In this
lesson, students will learn which questions they need to ask to
determine the accuracy and relevance of a poll.
Day One: Understanding the Mechanics of Polls
1.Ask students to define the term poll with respect to public
opinion. Have students discuss what they know about how a
poll is conducted. Discuss the purpose of polling: Who
conducts polls? Why are they done? How are polls used?
2.Distribute the Backgrounder: Understanding Public Opinion
Polls.
Review student understanding with the following
questions:
Historically, why and how were the Literary Digest poll of
1936 and the Gallup Poll of 1948 flawed? What lessons
about polling were learned from these two polling
mistakes?
In a poll, why must there be a clear and accurate link
between sample and population?
What are three criticisms of public opinion polls?
What are exit polls?
Why do most polls today rely primarily on phone banks?
Could instantaneous polls conducted via the Internet help
or hinder American politics? Why?
What is meant by "sampling error"?
3.Show Video Clip: Science of Public Opinion and follow up
with the discussion questions and activity from the March 21,
2000 CNN NEWSROOM classroom guide.
4.Divide students into groups of 3 or 4 and have each group
analyze one poll from CNN's AllPolitics
Each group should answer the following questions about their poll:
What is the poll asking?
When was it conducted?
Who was polled?
Why do you think this question was asked?
What were the results of the poll?
How did the writer reporting on the poll interpret theresults?
Did the statements report the facts? Provide
analysis? Inject opinion?
Homework: Distribute the following to students: Student Handout: CNN's Guidelines for Polling 20 Questions Journalists Should Ask About Polls
Have students read these two sources carefully to answer the
following questions:
How does CNN differentiate between a scientific and a non-scientific poll?
What criteria must be met before something can be labeled a scientific poll?
When analyzing poll results, what questions would you ask to determine if it is a poll you can trust?
Day Two: Critiquing Public Opinion Polls
Introduction: Now that students are familiar with why and how polls
are conducted, as critical viewers of the media, they will need to know
how to differentiate among the various polls.
1.Review homework assignment.
2.Once again, divide students into groups of 3 or 4 and distribute
a recent poll to each group. Students should analyze each poll
according to the CNN rules and the Public Agenda 20
Questions. In their final analysis, they should determine: "Is this
a poll voters should trust?"
3.Now examine the "polls" offered on this Your Choice. Your
Voice. site. Based on the CNN Rules and the Public Agenda
20 Questions
critique the polls posted on Your Choice. Your
Voice. Do they adhere to the criteria for a scientific poll? Why
or why not? How would you revise them to meet the polling
criteria? (Note: These "polls" were created to take a quick vote
on where students, participating in the CNN Your Choice. Your
Voice. campaign, stood on issues related to the curriculum.
We left the term "poll" to serve as a good lesson on the
importance of being a critical viewer.)
4.Collect several polls from newspapers, Internet and television
news. First, have students determine if it is a scientific or
non-scientific poll. Then ask students the following questions:
If you were a reporter, how would you write about these
poll results? What would your headline be?
If you were a candidate, how would you use this poll
information? What would the focus of your speech be?
If you were a voter, how would you use this information?
Would it affect your vote?
ASSESSMENT
As a wrap up to the unit, students should create a Q&A for voters who
want to know how they should interpret the polls they see and read
during an election. This brief introduction to polling should include a
definition of polls, a who, what, where, when and why of polls, and a
"Top Ten questions to ask before you let a poll result influence your
vote."
