Question four
Advantages of a focus group
The first main advantage of a focus group is that it involves using a moderator who intervenes every now and then to ensure that the discussion is on the right track and ensure that all participants are involved. Unlike other methods of gathering data, a focus group ensures that the group members interact with one another therefore enriching each other with new ideas. The method is also unique in that it’s flexible where the moderator can change the topic of discussion from time to time to ensure that he gets the best response. Compared to other methods, focus groups are advantageous in that enable the moderator to use non verbal behaviors as part of the research. This is done by observing the facial expression of the group members. All group members are always under keen observation by the moderator and this increases the level of participation by all the members. Focus groups ensure that information is provided more quickly compared to when the group members would be interviewed separately. Most data collection techniques are difficult for lay people to understand but this is not the case with focus groups where the results are very simple to understand.
