Sampling: Definition is defined as the process of selecting certain members or a subset of the population to make statistical inferences from them and to estimate characteristics of the whole population. Sampling is widely used by researchers in so that they do not need to research the entire population to collect actionable insights. It is also a time-convenient and a cost-effective method and hence forms the basis of any.
For example, if a drug manufacturer would like to research the adverse side effects of a drug on the population of the country, it is close to impossible to be able to conduct a research study that involves everyone. In this case, the researcher decides a sample of people from each and then conducts the research on them which gives them an indicative feedback on the behavior of the drug on the population. Types of Sampling: Sampling Methods Any market research study requires two essential types of sampling. They are: • Probability Sampling: s a sampling method that selects random members of a population by setting a few selection criteria. These selection parameters allow every member to have the equal opportunities to be a part of various samples.
• Non-probability Sampling: sampling method is reliant on a researcher’s ability to select members at random. This sampling method is not a fixed or pre-defined selection process which makes it difficult for all elements of a population to have equal opportunities to be included in a sample. In this blog, we discuss the various probability and non-probability sampling methods that can be implemented in any study.
Types of Sampling: Probability Sampling Methods is a sampling technique in which sample from a larger population are chosen using a method based on the theory of probability. This sampling method considers every member of the population and forms samples on the basis of a fixed process. For example, in a population of 1000 members, each of these members will have 1/1000 chances of being selected to be a part of a sample. It gets rid of bias in the population and gives a fair chance to all members to be included in the sample. There are 4 types of probability sampling technique: • Simple Random Sampling: One of the best probability sampling techniques that helps in saving time and resources, is the method. It is a trustworthy method of obtaining information where every single member of a population is chosen randomly, merely by chance and each individual has the exact same probability of being chosen to be a part of a sample.
