With purposive sampling,the researcher consciously selects certain participants to include in the study and may or may not include all typical subject types.Network sampling takes advantage of social networks and the fact that friends tend to have characteristics in common.Quota sampling involves techniques to ensure that certain subject types are represented to improve the representativeness of the total population.Theoretical sampling is used in qualitative research to develop a selected theory and subjects are selected based on their ability to provide relevant,varied,and rich information for theory generation.
