Final answer:
The best data collection methods for a respondent who needs to watch a twenty-minute infomercial would be in-home, online, or in-office interviewing, where person-administered techniques can ensure attention to the content and immediate feedback.
Step-by-step explanation:
If a respondent needs to watch a twenty-minute infomercial, the data collection methods that might be chosen to gather feedback would be methods that ensure the respondent has the time and setting to watch the content entirely. Considering the options provided, E) in-home, online or in-office interviewing methods would be the most appropriate since they can offer the respondent a controlled environment to watch the infomercial without interruptions. This setup also allows for immediate collection of data right after the viewing.
Person-administered methods are significant in such scenarios as they involve a direct interaction between the interviewer and the respondent, enhancing the reliability of the collected data. Face-to-face settings such as in-home or in-office interviews could facilitate this person-administration method effectively.
The administered survey aspect is crucial to ensure that the respondents are indeed watching the infomercial and providing immediate reactions or responses to it. Online methodologies can also provide a platform for viewing and immediate response, capturing the respondent's feedback in real-time. Therefore, a combination of these administering methods would result in efficient data collection for the given task.
