Purposive sampling Research Methodology. When a statistic (a function) is being used for a specific purpose, it may be referred to by a name indicating its purpose: in descriptive statistics, a descriptive statistic is used to describe the data; in estimation theory, an estimator is used to estimate a parameter of the distribution (population); in statistical hypothesis testing, a test statistic is used to test a hypothesis. When the population members are similar to one another on The sampling has a number of advantages as compared to complete enumeration due to a variety of reasons. This is the reason why they are purposively chosen as subjects. Sampling may be defined as the procedure in which a sample is selected from an individual or a group of people of certain kind for research purpose. We obtain a sample rather than a complete enumeration (a census) of the population for many reasons. As there are lack of experts to plan and conduct a sample survey, its execution and analysis, and its results would be unsatisfactory and not trustworthy. One of the main disadvantages of SRS is that it can be time-consuming and costly to identify and contact every member of the population. The organization and administration of sample survey are easy for the reasons which have been discussed earlier. uncooperative subjects.

Census method is necessary in some cases like population census, Agriculture Census, animal census etc for gaining vast knowledge. These disadvantages include the time needed to gather the full list of a specific population, the capital necessary to retrieve and contact that list, and the bias that could occur when the sample set is not large enough to adequately represent the full population. For example, a researcher can use critical case sampling to determine if a phenomenon is worth investigating further. 1.3 Limitations for Monte Carlo Methods Rejection sampling and importance sampling may not work well in high dimensions. In straightforward terms, Sampling is the course of determination of the set number of components from a huge gathering of components (population) so that, the qualities of the Samples taken is indistinguishable from that of the population.

The narrowness of the questions used will reflect the researchers particular stance on a subject far more than a random sample. Paramount among the problems encountered in the field are re- fusals, the inability of families to give the desired information, and unsuccessful attempts to contact families. Judgmental sampling, also called purposive sampling or authoritative sampling, is a non-probability sampling technique in which the sample members are chosen only on the basis of the researcher's knowledge and judgment. Much Easier. What are the advantages of sampling? For studying a social problem, it is difficult to study the whole universe of the problem under study.

Advantages of Non-Probability Sampling Probability Sampling methods give a very small space for judgment. Ideally, the sample corresponds to the larger population on the characteristic(s) of interest. For example, if you knew the proportion of pensioners in an area was 30% and you wanted to represent this in your sample you would ensure that pensioners' answers only made up 30% of your sample.

Scope of sampling is high. The classic example of this advantage is that critical sample can be useful in determining the value of an investigation, while the expert sampling approach allows for an in-depth analysis of the information that is present. Process of Quota Sampling. So, the cost will be lower if data is collected for a sample of population which is a big advantage. Advantages of sampling Low cost of sampling. For example, the sample mean is a statistic that estimates the population mean, which is a parameter. Within a population, a parameter is a fixed value which does not vary. 2.

Research is of value only when the findings from a sample can be generalized to a meaningful population. But manageable samples permit the researcher to establish adequate rapport with the respondents. A person with sound knowledge and ability on the subject matter can best perform if the person is permitted to conduct non-probability sampling.

Probability and non-probability sampling are two common sampling methodologies. Bias arises when the method of selection of sample employed is faulty. Organizational problems involved in sampling are very few. Disadvantages of sampling may be discussed under the heads: The serious limitation of the sampling method is that it involves biased selection and thereby leads us to draw erroneous conclusions. The choice of a mixed methods approach was relevant to (1) complement the methods in order to minimize the disadvantages of one approach over the other and utilize the advantages of each method and (2) triangulating the findings so they can be mutually corroborated (Bryman, 2006).
