Detailed explanation-1: -Snowball sampling is a recruitment technique in which research participants are asked to assist researchers in identifying other potential subjects.

Detailed explanation-2: -After the targets participate in the study, the researcher asks the participants to give recommendations on other people in the target population. The researcher contacts the recommended potential participants in the target population and asks them to participate in the study.

Detailed explanation-3: -Snowball sampling enables researchers to conduct studies when finding participants might otherwise be challenging. Concealed individuals, such as drug users or sex workers, are difficult for researchers to access, but snowball sampling helps researchers to connect to these hidden populations.

Detailed explanation-4: -The researcher then observes the nominated subjects and continues in the same way until the obtaining sufficient number of subjects.
