Purposive sampling may be the only appropriate method available if there are only limited number of primary data sources who can contribute to the study. Among the disadvantages are difficulty gaining access to a list of a larger population, time, costs, and that bias can still occur under certain circumstances. Disadvantages One of the biggest downsides of systematic sampling is the poor quality of sample if the population has periodicity ( Iachan, 1982) Therefore, in a population that does not have randomly occurring data, it cannot be administered. The snowball sampling method is extensively used where a population is unknown and rare and it is tough to choose subjects to assemble them as samples for research.
