What is Exponential Non-Discriminative Snowball Sampling?

Exponential Non-Discriminative Snowball Sampling is a technique used in qualitative research to gather data from participants through a network of referrals. Initially, a small number of subjects are selected, and these subjects then recruit additional participants from their own networks, creating a "snowball" effect. The "exponential" aspect refers to the rapid growth of the sample size as more participants are added; "non-discriminative" indicates that the sampling does not prioritize specific characteristics or criteria among the subjects. This method is particularly useful for reaching hidden or hard-to-access populations.
