Final answer:
The statement 'It reveals the way social meanings are jointly constructed' is not a limitation but a strength of the focus group method. Limitations include control issues, data complexity, and social desirability bias.
Step-by-step explanation:
The limitation of the focus group method that is not accurate within the options provided is the statement that it 'reveals the way social meanings are jointly constructed.' This aspect is not a limitation but a strength of focus groups, as they allow for the dynamic exploration of the creation and understanding of shared meanings among participants.
Focus group discussions are a qualitative research technique used to collect data through group interaction on a topic determined by the researcher. Some recognized limitations include the difficulty in controlling the direction of the discussion, the potential for the production of large volumes of complex data that are time-consuming to analyze, and the tendency for individuals to conform to group norms or express socially desirable views.
In contrast to the focus group method, random sampling helps ensure every potential participant has an equal chance of being selected, thus minimizing bias and potentially improving the generalizability of the results. Therefore, statement 'b' is the incorrect choice regarding the limitations of focus groups, as it is describing an advantage rather than a shortcoming of the method.
