What are the scientific public opinion polls?
Public opinion surveys serve as a conduit between the general public and elected authorities. Members of Congress frequently use polls to learn what their constituents' opinions are, but they also need to be aware of other political factors.
A random sample of the population must be used in an opinion poll, together with questions that are asked objectively to ensure that the results are reliable.
The most obvious distinction between an open-access poll and a scientific poll is that the samples in scientific polls are frequently chosen at random and occasionally weighted statistically to ensure that they are representative of the target population.
