For this reason, there are two types of sampling: the random or probabilistic sample and the non-probabilistic one. The sample size can be relatively small of excessively large depending on the decision making of the researcher. This method of identifying potential participants is not commonly used in research as it is in statistics because it can introduce bias into the findings. Since the sample is not chosen through random selection, it is impossible that your sample will be fully representative of the population being studied. This method is used to reduce bias or by researchers who wish to collect data quickly and easily. Although statisticians prefer probability sampling because it yields data in the form of numbers, however, if done correctly, it can produce similar if not the same quality of results. Its an efficient solution to generate data that can be used to represent a larger population. When they are one with a customer, they proceed to another customer.

If the researcher is interested in a particular department within the population the researcher will use quota sampling to divide the population into strata or groups. In this article, wed show you how to get a heterogenous sample for diverse data and also touch on the different types of stratified sampling. Therefore, the results of the research cannot be used in generalizations pertaining to the entire population. One of the major advantages of stratified sampling is it allows you to create a diverse research sample that represents every group in your population of interest. Researchers use it when they have limited time to conduct research or have budget constraints. Lastly, it is easier to find members to participate in a non-probability sampling because they have similar traits. You must have JavaScript enabled to use this form.
