What Is Quota Sampling In Sociology

With stratified random sampling the researcher needs a sampling frame from which to identify select and contact people in the sample. A quota sample is one in which units are selected into a sample on the basis of pre specified characteristics so that the total sample has the same distribution of characteristics assumed to exist in the population being studied. Cluster or multi stage sampling.

What is quota sampling in sociology. Quota sampling is defined as a non probability sampling method in which researchers create a sample involving individuals that represent a population. Quota sampling method is a non probability sampling and it can be defined as a sampling method of gathering representative data from a group. Stratified quota sampling this variation involves the same basic technique as stratified random sampling but with two main differences. Quota sampling is a sampling methodology wherein data is collected from a homogeneous group.

That is units are selected into a sample on the basis of pre specified characteristics so that the total sample has the same distribution of characteristics assumed to exist in the population being studied. A quota sample is a type of non probability sample in which the researcher selects people according to some fixed standard. Quota sampling has both advantages and disadvantages. Sometimes non random and unrepresentative sampling methods may be preferred despite the danger of unreliability.

While this is always useful it s not strictly necessary for quota sampling. It involves a two step process where two variables can be used to filter information from the population. Application of quota sampling ensures that sample group represents certain characteristics of the population chosen by the researcher. Researchers choose these individuals according to specific traits or qualities.

Although random sampling is seen as a representative method there are some research topics where researchers want to be careful that. Households may be randomly selected from a random sample of streets from a random selection of areas. It can easily be administered and helps in quick comparison. The researcher might then find these 30 by going to a job centre.

In this method researchers will be told to ensure the sample fits with certain quotas for example they might be told to find 90 participants with 30 of them being unemployed. Another advantage of quota sampling is it gives a better representation of certain groups within the population without over representing them. Quota sampling is mainly used by market researchers in. They decide and create quotas so that the market research samples can be useful in collecting data.

The purpose of sampling in sociology is generally to ensure that the subjects of the research are representative of a larger group the target population and therefore the results can be generalised. The problem of representativeness is again a problem with the quota sampling method.
