Question 38 • AP US Government and Politics

Which of the following is the best example of a scientifically conducted poll?

Answer

A small, private college in the Midwest emails a survey to its alumni asking about their views on a new environmental policy.

A political party mails a survey to its donors asking which issues it should focus on in the upcoming election.

An interest group conducts a random telephone survey asking likely voters if they approve of an education bill as written.

A large newspaper conducts a survey on its website asking readers whether the government should increase or decrease tariffs.

Explanation

A scientifically conducted poll uses a random sample of the relevant population so that people have a fair chance of being selected. Choice C uses a random telephone survey of likely voters, the group relevant to the question about the bill. The other choices survey limited or self-selected groups, such as alumni, donors, or newspaper website readers, so their results may not represent the broader public.
