when to use quota sampling

In this study we aim to test whether results from a quota sample, believed to be the non-probability sampling method that is the closest in representativeness to probability sampling, are statistically equivalent to those from a probability sample. First, you need to understand the difference between a population and a sample, and identify the target population of your research. Quota sampling, a non-probability sampling method, is a viable approach to serve the needs of the researcher. It can be very broad or quite narro… You don't need our permission to copy the article; just include a link/reference back to this page. Login failed. However, a disadvantage of quota sampling is it makes it impossible to detect a potential sampling error, since … 1. For these reasons, we do not think quota sampling should be taken as an acceptable alternative to probability sampling. In a study that considers gender, socioeconomic status and religion as the basis of the subgroups, the final sample may have skewed representation of age, race, educational attainment, marital status and a lot more. Further, we pay special attention to the effects of the following two factors for understanding the difference between the two sampling methods: the survey's topic and the response rate. Finally, the researcher selects subjects from the various subgroups while taking into consideration the proportions noted in the previous step. It involves a two-step process where two variables can be used to filter information from the population. Quota sampling: In Quota sampling, the selection of members in this sampling technique happens based on a pre-set standard. The increase of costs and the decline of response rates for administering probability samples have led some survey researchers to search for a non-probability sampling method as an alternative to probability sampling. Quota sampling is defined as a non-probability sampling method in which researchers create a sample involving individuals that represent a population. Another advantage of quota sampling is it gives a better representation of certain groups within the population, without over-representing them. type of non-probability sampling that involves a two-step process: Step 1: Specify a list of relevant control categories or quotas such as age The population can be defined in terms of geographical location, age, income, and many other characteristics. For example, job interviewers with a limited time frame to hire specific types of individuals can use quota sampling.

Quota sampling has both advantages and disadvantages. 1. These features make quota sampling a useful tactic for field research.

If a study aims to investigate a trait or a characteristic of a certain subgroup, this type of sampling is the ideal technique. It can easily be administered and helps in quick comparison.

Then judgement is used to select the subjects or units from each segment based on a specified proportion. It is a rapid method of collecting samples. Using the quota sample makes the comparison of these groups easy. It also allows the researcher to study traits and characteristics that are noted for each subgroup. Researchers choose these individuals according to specific traits or qualities. Quota sampling is the non-probability equivalent of stratified sampling. eval(ez_write_tag([[300,250],'explorable_com-medrectangle-4','ezslot_1',340,'0','0']));In addition to this, the researcher must make sure that the composition of the final sample to be used in the study meets the research's quota criteria.
