Which data collection method involves gathering information from multiple sources to identify trends and opinions?

The method of gathering information from multiple sources to identify trends and opinions is best represented by focus groups. Focus groups typically involve a small group of participants who discuss a particular topic guided by a moderator. This method allows for the collection of diverse perspectives and insights, facilitating the exploration of opinions and trends among the group members. The interaction among participants can lead to a richer understanding of the subject matter being investigated.

This method is particularly effective for capturing nuanced opinions and can uncover underlying emotions or motivations that may not emerge through other data collection techniques. By examining the dynamics of group discussion, researchers can identify common themes, consensus, or divergent views regarding the topic in question.

Other methods, while useful for data collection, may not provide the same depth of insight through the collaborative exchange of ideas that focus groups offer. For instance, surveys are typically more structured and may not allow for follow-up questions or deeper discussions. Archival data involves analyzing existing records, which might not capture current opinions. Key informant interviews, while informative, often focus on individual perspectives rather than a collective trend analysis that can be drawn from multiple participant interactions.
