Sampling is to extract individuals or samples from totality. Namely, it is a process of testing or observing the totality. There are two types of sampling: random sampling and non-random sampling. The former is to extract samples from totality in randomization principle. This method has no subjectivity and it can be classified to be simple random sampling, system sampling, cluster sampling and stratified sampling. The latter is a subjective method of extracting samples depending on researcher’s opinion, experience or relevant knowledge.
