Editing Snowball sampling (section)

==Description==

Snowball sampling uses a small pool of initial informants to nominate, through their social networks, other participants who meet the eligibility criteria and could potentially contribute to a specific study. The term "snowball sampling" reflects an analogy to a snowball increasing in size as it rolls downhill.<ref>{{cite book|last1= David L. |first1=Morgan |year=2008 |title= The SAGE Encyclopedia of Qualitative Research Methods |isbn= 9781412941631|pages= 816–817 |publisher= SAGE Publications, Inc}}</ref>

===Method===

#Draft a participation program (likely to be subject to change, but indicative).
#Approach stakeholders and ask for contacts.
#Gain contacts and ask them to participate.
#Community issues groups may emerge that can be included in the participation program.
#Continue the snowballing with contacts to gain more stakeholders if necessary.
#Ensure a diversity of contacts by widening the profile of persons involved in the snowballing exercise.
