This method of sampling is also known as subjective or judgment sampling method. Theory of sampling focuses on improving the efficiency of sampling. For example, the mean of the data in a sample is used to give information about the overall mean in the population from which that sample was drawn. Some fundamental concepts related to sampling are discussed as follows: The total number of items in any field of study is called the universe. The narrowness of the questions used will reflect the researchers particular stance on a subject far more than a random sample. 3. :9fk*\T1#,9}>8etCEkdTm4#A=. Organization of convenience. individuals, Possibly, members of units are different from one another, strata in the population. But manageable samples permit the researcher to establish adequate rapport with the respondents. Before the measurement has been completed, the population would have changed. The selection criteria the researcher uses can be very arbitrary and are almost always subjective. * Probability sampling includes: Simple Random Sampling, Systematic Sampling, Stratified Random Sampling, Cluster Sampling Multistage Sampling. . With judgmental sampling, the researcher believes that some subjects are more fit for the research compared to other individuals. However, those methods also come with some potential drawbacks. The convenience sampling method was chosen due to its simplicity, ease of use, and prevalence among . Greater Speed. 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. The resources available within an organization may be limited. What is a disadvantage of stratified sampling? 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. Reduce Cost. 16. To understand more about purposive sampling, the different types of purposive sampling, and the advantages and disadvantages of this non-probability sampling technique, see the article: Purposive sampling. Advantages of Sample Surveys compared with Censuses: Reduces cost both in monetary terms and staffing requirements. Convenience Sampling. This will be either to base on religion, age, education gender; etc. Testing of accuracy of samples drawn can be made by comparing two or more samples. Advantages of Non-Probability Sampling. Online surveys commonly suffer from two serious methodological limitations: the population to which they are distributed cannot be described, and respondents with biases may select themselves into the sample.

Advantages More accurate Useful in specific circumstances to serve the purpose. 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. Because the generalizability of convenience samples is unclear, the estimates derived from convenience samples are often biased (i.e., sample estimates are not reflective of true effects among the target population because the sample poorly represents the target population). We obtain a sample rather than a complete enumeration (a census) of the population for many reasons. Various disadvantages of sampling process are discussed in points given below: . Sampling saves money by allowing researchers to gather the same answers from a sample that they would receive from the population. In simple random sampling, an accurate statistical measure of a large population can only be obtained when a full list of the entire population to be studied is available. HTMo1Wh!
