Sampling can be defined as the process through which individuals or sampling units are selected from the sample frame. The sampling plan of action needs to be specified in advance, given that the sampling method may affect the sample size estimation. Without a careful sampling plan the results derived from the study may be biased. Hence the need for diverse sampling inorder to promote the studies external validity.
