RESEARCH METHODOLOGY

Detailed explanation-1: -"Snowball” sampling: in this case, the researcher selects an initial group of individuals. Then, these participants indicate other potential members with similar characteristics to take part in the study.

Detailed explanation-2: -Snowball sampling is a recruitment technique in which research participants are asked to assist researchers in identifying other potential subjects.

Detailed explanation-3: -Snowball sampling or chain-referral sampling is defined as a non-probability sampling technique in which the samples have rare traits. This is a sampling technique, in which existing subjects provide referrals to recruit samples required for a research study.

Detailed explanation-4: -Referral sampling usually involves identifying individuals who meet inclusion criteria, gaining their cooperation, and then asking them to recruit additional respondents with the same conditions (Heckathorn 2002).

Detailed explanation-5: -Convenience of Snowball Sampling As a form of convenience sampling, snowball sampling is often combined with purposive sampling, and to a lesser extent quota sampling, whereby participants are selected based upon their specific characteristics or membership of a group.
