Simple random sampling is when every member of the population has an equal chance of selection for the sample.
Cluster sampling occurs when a researcher develops a sampling frame that consists of a larger division than the one desired and it is chosen randomly, then subjects from the chosen subsets are selected randomly.
A convenience sample is not a random sample; it is based on any member of the target population that is easily accessible to the researcher.
In a stratified sample, knowledge about characteristics of the population is used to create representativeness.
