We also had an initial purposivesample of 27 studies, provided by an expert in the field. A purposivesample of 27 staff were interviewed using a partially structured interview format. The fieldwork involved nonparticipant observation, in-depth interviews with a purposivesample of public and voluntary sector workers and document analysis. First, the sample was a convenient purposivesample that was relative homogeneous with respect to their homeless state, and not randomly selected or matched. A nonprobability purposivesample was utilised, since the research was meant to be illustrative and not representative.
