Enhancing the sample diversity of snowball samples: Recommendations from a research project on anti-dam movements in Southeast Asia.
Snowball sampling is a commonly employed sampling method in qualitative research; however, the diversity of samples generated via this method has repeatedly been questioned. Scholars have posited several anecdotally based recommendations for enhancing the diversity of snowball samples. In this study...
