Purposive sampling means seeking out and consenting study participants in a purposeful manner
Purposive sampling is a non-probability sampling method where researchers seek out individuals from a given population of interest that possess certain types of characteristics that are defined as inclusion and exclusion critiera.

Since members are being sought out in purposive sampling, a lot of observational and selection biases are introduced into the study.
