Question

Which of these BEST describes how public opinion is usually researched in the United States?
A) One entire state is surveyed.
B) The entire male population is surveyed.
C) Every person in the population is surveyed.
D) A random sample of the population is surveyed.

Answer 1

The answer is D. When doing surveys, you must have an unbiased choice of people, or else, the survey is invalid.

Answer 2

Answer:

The answer is D) A random sample of the population is surveyed

Explanation:

Although surveying every person in a population would give researchers the most accurate data, it would be nearly impossible to survey that many people. When a random sample of the population is surveyed, researchers still get fairly accurate information about the population as a whole.
