Qualitative sampling may begin with volunteer participants, but many studies eventually evolve to a broad sampling strategy focused on the study's information needs. what is the name of that broad strategy?

Purposive sampling

Explanation:

Purposive sampling, which is also referred to as a selective or subjective Samling, is a non probability sampling in which participants are chosen with consideration of what the study is about and their characteristics.

This can be vital form of sampling if the response or the results are needed immediately and when the number of participants is not a concern.

So it is subjective based on what the researcher wants to find out because participants are not randomly picked but they have to be in line with the aim of the research.
