When to use it. Ensures a high degree of representativeness, and no need to use a table of random numbers. When the population is heterogeneous and contains several different groups, some of which are related to the topic of the study. Ensures a high degree of representativeness of all the strata or layers in the population.
Convenience Samples: Pros and Cons
Convenience sampling is a method of non-probability sampling that involves the participants being drawn from a close population group. It may be referred to as accidental, opportunity, or grab sampling by some researchers, instructors, or participants. Data gathering with this method comes from people that are the easiest to reach or contact. If someone has ever tried to get you to take a survey while you shop at a mall, then that action was a form of convenience sampling. No criteria are in place for this sampling method beyond the willingness and availability of people to participate in the work. Several convenience sampling advantages and disadvantages are worth reviewing when looking at this form of data gathering. Convenience sampling is an affordable way to gather data.
Home QuestionPro Products Audience. Definition: Convenience sampling is defined as a method adopted by researchers where they collect market research data from a conveniently available pool of respondents. In many cases, members are readily approachable to be a part of the sample. Researchers use various sampling techniques in situations where there are large populations. In most cases, testing the entire community is practically impossible because they are not easy to reach. Researchers use convenience sampling in situations where additional inputs are not necessary for the principal research. There are no criteria required to be a part of this sample.
Convenience Samples for Research
Non-probability sampling derives its control from the judgement of the investigator. In non-probability sampling, the cases are selected on bases of availability and interviewer judgement. Non-probability sampling has its strength in the area of convenience. Convenience sampling is generally known as careless, unsystematic, accidental or opportunistic sampling. The sample is selected according to the convenience of the sample. The researcher selects certain units convenient to him. It requires no pre-planning for the selection of items.
Disadvantages of Convenience Sampling. Highly vulnerable to selection bias and influences beyond the control of the researcher. High level of sampling error. Studies that use convenience sampling have little credibility due to reasons above.
Convenience sampling is a type of non-probability sampling technique. Non-probability sampling focuses on sampling techniques that are based on the judgement of the researcher [see our article Non-probability sampling to learn more about non-probability sampling]. This article explains a what convenience sampling is and b the advantages and disadvantages limitations of convenience sampling. Imagine that a researcher wants to understand more about the career goals of students at the University of Bath. These 10, students are our population N.
A convenience sample is a non-probability sample in which the researcher uses the subjects that are nearest and available to participate in the research study. This technique is also referred to as "accidental sampling," and is commonly used in pilot studies prior to launching a larger research project. When a researcher is eager to begin conducting research with people as subjects, but may not have a large budget or the time and resources that would allow for the creation of a large, randomized sample, she may choose to use the technique of convenience sampling. It could also mean surveying friends, students, or colleagues to which the researcher has regular access. Given that social science researchers are also often college or university professors, it is quite common for them to begin research projects by inviting their students to be participants.
