Quota sampling involves convenience sampling but adds techniques to ensure that certain subject types are represented.Cluster sampling occurs when the researcher selects subjects from groups of subjects within the larger population,as with groups from specific regions or cities.Network sampling uses social networks to obtain subjects who might not be readily accessible otherwise.Theoretical sampling is used in qualitative research to develop a selected theory.Subjects are selected based on their ability to provide relevant,varied,and rich information for theory generation.
