In a non-probability sample individuals are selected based on non-random criteria and not every individual has a chance of being included.
Snowball sampling is a non-probability sampling method where currently enrolled research participants help recruit future subjects for a study. That means the inferences you can make about the population are weaker than. This type of sample is easier and cheaper to access but it has a higher risk of sampling bias.
