My Pleasure.
We have discussed these questions earlier in the relevent sections but i repeat again.
1- Survey type of research design is used for these categories of people by using an interview schedule/questioner for data collection.
2- It depends on the objectives of the research.
3- When we have no or little knowledge about the section of a population, we prefer survey to get the basic data first.
Plz e-mail me for further discussion on these or other topics related with sociology.
