Who do you think is more interested in using a random sampling method: A pollster running a political campaign or an experimental researcher who is studying a cause-and-effect relationship between two variables? Explain your answer. - With the random sampling method, I believe the researcher would benefit more from using it. Even though it is random, some of these samples might tend to have a slightly higher percentage of Democrats (or Republicans) than does the general population; some samples might include more older people and some samples might include more younger people, which might not be a fair and even reflection.
