In most real applied social research, we would use sampling methods that are considerably more complex than these simple variations the most important principle here is that we can combine the simple methods described earlier in a variety of useful ways that help us address our sampling needs in the most efficient and effective manner possible. This type of research is called a census study because data is gathered on every member of the population sampling methods are classified as either probability .
While choosing one of these methods could result in biased data or a limited ability to make general inferences based on the findings, there are also many situations in which choosing this kind of sampling technique is the best choice for the particular research question or the stage of research.

Types of sampling methods and techniques in research the main goal of any marketing or statistical research is to provide quality results that are a reliable basis for decision-making that is why the different types of sampling methods and techniques have a crucial role in research methodology and statistics. Then, because some types of sampling rely upon quantitative models, we'll talk about some of the statistical terms used in sampling finally, we'll discuss the major distinction between probability and nonprobability sampling methods and work through the major types in each.
What are the main types of sampling and how is each done simple random sampling: a simple random sample (srs) of size n is produced by a scheme which ensures that each subgroup of the population of size n has an equal probability of being chosen as the sample.
