Purposive sampling involves selecting participants based on a specific characteristic or criterion relevant to the research question. In this case, Hiro is interested in studying hamster owners, and he uses the National Hamster Owners Association to recruit participants who fit this criterion. Option A does not necessarily involve purposive sampling, as there may be a specific reason for studying hamster owners rather than pet owners in general. Option C is convenience sampling, as it involves selecting participants based on their availability and accessibility rather than a specific criterion. Option D is snowball sampling, as it involves asking participants to refer other potential participants who fit the criterion being studied.
