Snowball sampling is the process of getting participants through referrals from other participants. Since Ella started with a small group of lesbian couples who have adopted in the past and used their referrals to obtain more participants, this is an example of snowball sampling. Simple random sampling involves randomly selecting participants from a larger population, convenience sampling involves selecting participants who are easily available or accessible, systematic sampling involves selecting every nth unit from a list, and multistage cluster sampling involves selecting participants from a series of groupings (such as selecting states randomly, then selecting cities randomly within those states). None of these methods accurately describe the process Ella used to select her sample.
