Question

at the bottom of the article, maximize the box titled \survey methods.\ which of the following is an accurate statement regarding the methodology gallup used to study and report its findings on u.s. political ideology?

gallup conducted surveys of all u.s. households over the course of the year.

gallup took no additional measures to avoid sampling error.

gallup used a sample of u.s. adults to infer the ideological leanings of the u.s. adult population as a whole.

gallup only surveyed respondents with a landline telephone because current random - dial technology excludes mobile phones.

gallup asked listeners to its news program to call in and take the survey.

Explanation:

• Option 1: Surveying all U.S. households (census - like) is impractical for Gallup; they use sampling, so this is incorrect.
• Option 2: Gallup does take measures to minimize sampling error (e.g., proper sampling techniques), so this is false.
• Option 3: Gallup typically uses a sample of U.S. adults to make inferences about the entire adult population, which is a standard survey methodology. This is accurate.
• Option 4: Modern Gallup surveys include mobile phones, so this is incorrect.
• Option 5: Call - in surveys from news programs are non - random and biased, not how Gallup conducts surveys.

Answer:

C. Gallup used a sample of U.S. adults to infer the ideological leanings of the U.S. adult population as a whole.
