Final answer:
The method involving a small group discussion for research is a focus group, providing depth on subjects, although the results may not always apply broadly.
Step-by-step explanation:
The method that involves bringing a small number of people together in one place to discuss specific research topics is the focus group. A focus group is a qualitative research method where a group of people are asked about their perceptions, opinions, beliefs, and attitudes towards a product, service, concept, advertisement, idea, or packaging. Questions are asked in an interactive group setting where participants are free to talk with other group members. Unlike surveys, which can collect data from a large population, focus groups provide more depth on a particular subject. However, the small sample size may limit the generalizability of the results to the broader population. Personal interviews, on the other hand, consist of one-on-one interactions and are suitable for more detailed personal feedback. The Delphi method is a structured communication technique involving a panel of experts to gather insights on complex problems, and correlation analysis is a quantitative method that explores the potential relationships between variables. Analogy research involves comparing one phenomenon with another that is similar in some aspects to draw conclusions.
