SAMPLING TECHNIQUES INTRODUCTION. The advantages and disadvantages of random sampling show that it can be quite effective when it is performed correctly. Random sampling removes an unconscious bias while creating data that can be analyzed to benefit the general demographic or population group being studied. If controls can be in place to remove purposeful manipulation of the, Sampling has always been discussed on the basis of one classification; that is, probability sampling and non probability sampling. But there is another classification that is not commonly found in many research books. This is know as complex sampling.

Suppose there are N members of the, Simple random sampling is simple to accomplish and is easy to explain to others. Because simple random sampling is a fair way to select a sample, it is reasonable to generalize the results from the sample back to the population.

    To draw a probability sample, we begin by identifying the population of interest. The next step is to create the “sampling frame,” a list of units to be sampled. One easy design is “simple random sampling.” For instance, to draw a simple random sample of 100 units, choose one unit assume that a random sample was obtained just because the researcher used a random selection method at some point in the sampling process. Look for those two particular

    • The reciprocal of the sampling fraction is called the Raising Factor. • A sample, in which every unit has the same probability of selection, is called a random sample. If no repetitions are allowed, it is termed as a simple random sample selected without replacement. If repetitions are permitted, the sample is selected with replacement. Probability sampling is also called as random sampling or representative sampling. In probability sampling every member of the population has a known (non zero) probability of being included in the sample. Some form of random selection is used.
