Sampling means take one typical part of from the whole population, which is an essential method for corporations to get the result of their new products or policies. When corporations test the sample, they do not actually need the specific data and number. In addition, the total number of comprising the population is usually large, so the corporations usually do not test the whole population for reducing meaningless time and labor cost. Sampling is a good way to trade effectiveness to efficiency. Thus, the results of sampling are always directly connected with and also affected the applying or changing of products and polices of corporations.

There are two kinds of risk of sample, sampling risk and nonsampling risk, during the process of sampling. Sample always causes risk because the sample does not include all of the information of the whole population in the test. Thus, it is entirely possible that the sample does not show the correct result of examination to the test engagement team. For example, in the case of Wilson Corporation, the engagement team of Wilson tested 50 golfers as sample for calculating the distances for the new golf to make sure whether that Wilson’s golf balls provided an increase of distance.

This sampling would require that the sampling is relevant to the topic that we are trying to research and that there is an identifiable distribution among the population being interviewed. This would be required if you were to sample males versus females, one would have to be sure to determine the exact distribution level. It would be important to ensure that it was calculated that there were 45 males and 50 females and that information would have to be evaluated based on those measures rather than an equal amount of each. This could also be said if one were to interview different religious groups. If you were going to interview several different religious groups, it would be imperative to ensure that you have allowed all the numbers of the groupings that you have done.

According to Hair et al. (2003), in the research, the sampling process enables identifying, developing and understanding an interested object that need to be determined (p.333). Hence, in order for the researcher to carry out the sampling appropriately, advantages and disadvantages of the various sampling methods should be considered along with the theoretical component of the study (Hair et al. 2003, p. 368 f). Theoretically, the sampling procedure is divided into two major types which consist of probability and nonprobability sampling. In probability sampling, individuals have a known chance of being selected. While, in non-probability sampling, individuals do not have a known possibility to be selected (Sekaran 2003, p. 269 f). Also, the different sampling methods provide different advantages and disadvantages. Hence, the researcher should consider this point before choosing the sampling method for the
