The smaller the standard error, the more representative the sample will be of the overall population. A proper size of sample is maintained in order to have optimized results in terms of cost and efficiency. Instead, they collect data from a subset of individuals a sample and use those observations to make inferences about the entire population. However, a single statistic can be used for multiple purposes for example, the sample mean can be used to describe a data set, to estimate the population mean, or to test a hypothesis. Purposive sampling (also known as judgment, selective or subjective sampling) is a sampling technique in which researcher relies on his or her own judgment when choosing members of population to participate in the study. There will be chances of errors even if samples are drawn most carefully. Data for small geographical areas also may be too unreliable to be useful. Purposive sampling advantages and disadvantages pdf Utilization of specific questions to under 100 percent of the population(group of all things that we are attempting to notice and break down) is known as Sampling. Surveys vary in their purposes, in the methods they use for collecting data, and in the timeframes in which they operate (from the 24 hours for a political `eve of poll' survey, to the 10 years or so that it can take to publish some of the more complex census data).

For example, the . individuals, Possibly, members of units are different from one another, Since the forms and parameters are not ordinarily known, an estimate of these two characteristics of population is made from the sample distribution. The purpose of sampling theory is to make sampling more efficient. Sampling guarantees accommodation, an assortment of concentrated and thorough data, suitability in restricted assets and better compatibility. Reduces time needed to collect and process the data and produce results as it requires a smaller scale of operation.

Non-probability sampling is defined as a sampling technique in which the researcher selects samples based on the subjective judgment of the researcher rather than random selection. Stratified random sampling is a type of probability sampling technique [see our article Probability sampling if you do not know what probability sampling is]. In sampling, though the number of cases is small, it is not always easy to stick to the, selected cases. Given that your decision on the Sampling strategies should be proper.

Sampling is most widely used in statistical testing where size of population is too large such that it is impossible to include each individual observation in test. The main disadvantage of purposive sampling is the high probability of researcher bias, as each sample is based entirely on the judgment of the researcher in question, who generally is trying to prove a specific point. A person with sound knowledge and ability on the subject matter can best perform if the person is permitted to conduct non-probability sampling. 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.

The total number of members of the population is called Population Size and the number included in the sample is called Sample Size. When the researcher lacks specialized knowledge in sampling, he may commit serious mistakes. Sampling error is the difference between a population parameter and a sample statistic used to estimate it. Sampling is therefore economical in respect of resources. The cost for collecting data about entire population is quite high. More formally, statistical theory defines a statistic as a function of a sample where the function itself is independent of the samples distribution; that is, the function can be stated before the realization of the data. Sampling reduces the population into small manageable units. Cluster sampling- she puts 50 into random groups of 5 so we get 10 groups then randomly selects 5 of them and interviews everyone in those groups --> 25 people are asked. !CPZ5f,/qB!ksq/&.@`|-pO&=i8OFdWqg~R`Ao?&QdL{30u'2r'-+AD0xY$s')/.@_1&^%P|?.A+:9-kIDOAdMtrC{^:M(wqGe%"OSpxX" 3 Disadvantage: Arbitrariness.

(Because of the above reasons) detailed cross-tabulations may not be practical. Learn the pros and cons of quota sampling in this article. 4 Disadvantage: Lost Data. It is a process of selecting an adequate number of elements from the population so that the study of the sample will not only help in understanding the characteristics of the population but will also enable us to generalize the results. The investigator is concerned with the generalization of data. It is calculated by applying a function (statistical algorithm) to the values of the items of the sample, which are known together as a set of data. A sample is a small proportion of a population.

The main purpose of the creation and present-day use of multi-stage sampling is to avoid the problems of randomly sampling from a population that is larger than the researcher's resources can handle. Stratified Sampling A method of sampling that involves the division of a population into smaller groups known strata.

Use of sampling method requires adequate subject specific knowledge in sampling technique. Greater Speed. Scope of sampling is high. Because random sampling takes a few from a large population, the ease of forming a sample group out of the larger frame is incredibly easy. This type of correspondence between the sample and the larger population is most important when a researcher wants to know what proportion of the population has a certain characteristic like a particular opinion or a demographic feature. It is a more complex form of cluster sampling, in which smaller groups are successively selected from large populations to form the sample population used in your study. 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.
