      Systematic sampling has the advantage that a sampling frame does not need to be assembled beforehand. In terms of Internet surveying, for example, systematic sampling can be used to sample sequential visitors to a website. The resulting sample is considered to be a probability sample as long as the sampling interval does not coincide with a

      underlying sampling strategies. Whether the study is a survey or an analytic study, how the study members are obtained from the population (i.e., the method of sampling) will determine the precision and nature of extrapolations from the sample to the population. Planning the sampling strategy is a major component of survey design.

For example, if your evaluation question is whether children are aware of the importance of brushing their teeth, the people who can best answer this question are the children themselves, so you would want to be sure that the method you choose is an appropriate tool for collecting information from children.

This method is also called unrestricted random sampling because units are selected from the population without any restriction. This method is mostly used in lottery draws. If the universe is

      Probability sampling is based on underlying theoretical distributions of observations, or sampling distributions, the best known of which is the normal curve. Random Sampling Random sampling is perhaps the most well known of all sampling strategies. A simple random sample is one is which each unit (e.g., persons, cases) in the accessible population

      Thus in our example, the randomly selected numbers are 2, 5 and 8 used to randomly sample the subjects in Figure 3-1. Since the random numbers are mutually exclusive (i.e., there are no duplicates), each person with the illustrated method is only sampled once. As described later in this chapter, such selection is sampling without replacement. -----

      While ISM is a reliable sampling technique that can be used at PCB cleanup sites, it may not be the most appropriate sampling technique for a specific site. For example, a discrete sampling method may be determined to be more appropriate for a site based on the characteristics of that particular site.
