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. For example, the sample mean is a statistic that estimates the population mean, which is a parameter. Greater Speed. but not so big that the process of sampling becomes uneconomical. This will be either to base on religion, age, education gender; etc. Sampling analysis involves estimating the parameter from the statistic.

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 researchers knowledge and judgment. Astatistic( singular) is a single measure of some attributes of a sample, for example, its arithmetic mean value. 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. Probability And Non Probability Sampling Cultural Studies The major setback of purposive sampling is that you necessity to agree on the specific features of the quota to base on. 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. By exercising judgment in who to sample, the researcher is able to save time and money when compared to broader sampling strategies.

Regional Training Course on Sampling Methods for Producing Core Data Items for Agricultural and Rural Statistics . The attributes that are the object of the study are called the characteristics and the units possessing them are known as elementary units. While choosing a sample, the population is assumed to be composed of individual units or members, some of which are included in the sample.

Characteristics, benefits, crucial issues/ draw backs, and examples of each sampling type are provided separately. hb```f``g`e`] ,@Q r00xt[DkgDtN @\9p10^EX Sampling method also furnishes a greater accuracy in problems where it is difficult to reach all members of a population, e.g., where persons or individuals are widely dispersed or live in relatively inaccessible areas. Among the disadvantages are difficulty gaining access to a list of a larger population, time, costs, and that bias can still occur under certain circumstances. 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. The narrowness of the questions used will reflect the researchers particular stance on a subject far more than a random sample.

Theory of sampling focuses on improving the efficiency of sampling. If the fertility rates of all the 30,000 people of the population are obtained and arranged in a frequency distribution, it is known as population distribution. 4. Data for small geographical areas also may be too unreliable to be useful. Advantages & Disadvantages of Sampling Method of Data Collection. Often the two terms are used interchangeably, however, research needs a distinction. Purposive sampling becomes useful in this situation, because it offers a wide selection of non-probability sampling techniques. In the absence of these the results of their search will be biased. Sampling error is the difference between a population parameter and a sample statistic used to estimate it. 1. It also introduces some risks of manipulation by researcher. This is in contrast to a random sample, where you choose subjects in some random fashion, and also in contrast to a convenience sample, where you pick subjects based on some convenient factor (e.g., they happen to be in your class that The total number of members of the population is called Population Size and the number included in the sample is called Sample Size. 6. Non probability sampling advantages and disadvantages pdf Quota sampling is a non-probability sampling technique in which researchers look for a specific characteristic in their respondents, and then take a tailored sample that is in proportion to a population of interest. For studying a social problem, it is difficult to study the whole universe of the problem under study. Tabulation, analysis etc., take much less time in the case of a sample than in the case of a population. Within a population, a parameter is a fixed value which does not vary. This method is cheaper than the Census Research because only a fraction of the population is studied in this method. With judgmental sampling, the researcher believes that some subjects are more fit for the research compared to other individuals. The selection criteria the researcher uses can be very arbitrary and are almost always subjective. The serious limitation of the sampling method is that it involves biased selection and thereby leads us to draw erroneous conclusions. Sampling is therefore economical in respect of resources.
