Simple random sampling is the most basic of the probability sampling plans and is achieved by randomly selecting elements from the sampling frame.It can be done by computer,as in this case.Cluster sampling occurs when the researcher selects subjects from groups of subjects within the larger population,as with groups from specific regions or cities.Stratified random sampling occurs by ensuring that the proportions of characteristics among the population are represented in both the control and experimental groups.Systematic sampling is used when an ordered list of all members of the population is available and involves selecting every kth individual on the list.
