SAMPLING METHODS. This document Sampling is the process of selecting a subset of individuals from within a population to estimate characteristics of the whole population. An event occurs if and only if the outcome of the is a member Convenience sampling saves time, money, and effort, but it is the least rigorous technique and may result in poor quality data and lacks intellectual credibility.
