Final answer:
The statement is false; choosing a random sample is crucial for the reliability and accuracy of polls because it represents the entire population and minimizes bias.
Step-by-step explanation:
Choosing a random sample is indeed a necessary and important part of polling to ensure the accuracy of the results. This statement in the question is false. Random samples are crucial because they represent the population as a whole, allowing for an accurate estimate of public opinion. For example, with a method like probability sampling, each member of the population has an equal chance of being included in the sample, which diminishes bias and increases representativeness. Although sometimes researchers use other methods such as convenience sampling or cluster sampling for practical reasons, these do not offer as accurate reflections of the broader public opinion as random sampling does. A correctly chosen random sample helps ensure that the poll is reliable and that its findings can be generalized to the entire population.
