For the claim that half of Americans show road rage to have strong external validity, which sample would be best to use?

To establish strong external validity for the claim that half of Americans show road rage, it is essential to have a sample that adequately represents the diverse population of American drivers. A cross-section of American drivers representing various demographics would ensure that the findings can be generalized to the broader population. This includes considering factors such as age, gender, ethnicity, socioeconomic status, and geographical locations, which all contribute to different experiences and expressions of road rage. By selecting a sample that captures this diversity, the study's conclusions are more likely to reflect the behaviors and attitudes of the entire American population rather than being limited to a specific subgroup. This broad representation is crucial for any claim about widespread behavior like road rage, as it validates the findings across different segments of society.
