“While you might have to do a dozen interviews to find out that what people are really worried about is X, because you did not know enough about the situation ahead of time to inquire about X, a good focus group, run by a good facilitator, will tend to ensure that X will come up if it’s sometime that the people you are studying really, truly are worried about.”
Focus groups are more interactive than surveys. My initial research methodology was to conduct surveys of the homeless population, but factoring in that they have no fixed address, no method of contact (email or telephone), I don’t think surveys would be the best option.
The more I look into it, the more I think focus groups would be a good choice for this kind of research. What do you guys think?
