In Reply to: Snowball or Purposive Sampling??? posted by kevin on February 19, 2000 at 13:01:07:
Purposive sampling simply means that the samples are selected for a particular reason. For instance, if you wanted to measure teachers' competencies, and your samples were recommended based on their practical teaching, then this is what we call purposive sampling.
I am not sure what snowball means.
