Final answer:
The researcher is trying to select a representative sample of college students for a study on attitudes about banning supersize sodas to ensure findings can be generalized to the broader U.S. college student population.
Step-by-step explanation:
The researcher is seeking to study college students' attitudes about banning supersize sodas and is aiming to select a sample that will closely reflect the entire population of college students in the United States. This means that the researcher is attempting to create a representative sample, which is a subset of individuals that closely mirrors the entire population.
The researcher would benefit from ensuring the sample includes a variety of students from different regions, socioeconomic backgrounds, and other demographic factors that can influence one's opinion on the topic. By doing so, the researcher enhances the chances that the findings from the sample can be generalized to the broader population of U.S. college students, thereby providing an accurate reflection of national college student attitudes about the issue.
