Detailed explanation-1: -Random sampling is one such procedure that selects a sample of units from a population by chance, typically to facilitate generalization from the sample to the population (Shadish, Cook, & Campbell, 2002).
Detailed explanation-2: -This way, statisticians and economists can make more confident inferences about a general population from the results obtained. Such samples must be representative of the chosen population studied. They must be randomly chosen, meaning that each member of the larger population has an equal chance of being chosen.
Detailed explanation-3: -The population to which general-izations are made in this way can be termed the target population-a set of elements larger than or different from the population that was sampled and to which the researcher would like to generalize any study findings.
Detailed explanation-4: -Simple random sampling. In simple random sampling (SRS), each sampling unit of a population has an equal chance of being included in the sample. Consequently, each possible sample also has an equal chance of being selected.
