Answer:
D. Focus groups allow for multiple viewpoints to be heard.
Step-by-step explanation:
A focus group is a form of recollecting data and information through various viewpoints within a group. It is commonly used in marketing or psychology even, in order to receive feedback from clients/ subjects for research.
Focus groups allow multiple viewpoints to be heard in order to optimize the product or get more information about a study, for example.
The other options are disadvantages;
- Since people need to be assembled, it can be difficult to set the right time and place for everyone.
- A moderator does require certain skills so not everyone can do it.
- They do afford the researcher less control since it is a group, not individual.
- The data tends to be hard to analyze.
