A simple random sample is used by researchers to statistically measure a subset of individuals selected from a larger group or population to approximate a response from the entire group.
This research method has both benefits and drawbacks. Unlike other forms of surveying techniques, simple random sampling is an unbiased approach to garner the responses from a large group. Although there are distinct advantages to using a simple random sample in research, it has inherent drawbacks.
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. Random sampling offers two primary advantages. Because individuals who make up the subset of the larger group are chosen at random, each individual in the large population set has the same probability of being selected. This creates, in most cases, a balanced subset that carries the greatest potential for representing the larger group as a whole.
As its name implies, producing a simple random sample is much less complicated than other methods , such as stratified random sampling. As mentioned, individuals in the subset are selected randomly and there are no additional steps. To ensure bias does not occur, researchers must acquire responses from an adequate number of respondents, which may not be possible due to time or budget constraints.
The drawbacks of this research method include:. 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. In some instances, details on a population of students at a university or a group of employees at a specific company are accessible through the organization that connects each population.
However, gaining access to the whole list can present challenges. Some universities or colleges are not willing to provide a complete list of students or faculty for research. Similarly, specific companies may not be willing or able to hand over information about employee groups due to privacy policies. When a full list of a larger population is not available, individuals attempting to conduct simple random sampling must gather information from other sources.
If publicly available, smaller subset lists can be used to recreate a full list of a larger population, but this strategy takes time to complete. Organizations that keep data on students, employees, and individual consumers often impose lengthy retrieval processes that can stall a researcher's ability to obtain the most accurate information on the entire population set.
In addition to the time it takes to gather information from various sources, the process may cost a company or individual a substantial amount of capital. Retrieving a full list of a population or smaller subset lists from a third-party data provider may require payment each time data is provided. If the sample is not large enough to represent the views of the entire population during the first round of simple random sampling, purchasing additional lists or databases to avoid a sampling error can be prohibitive.
Although simple random sampling is intended to be an unbiased approach to surveying, sample selection bias can occur. When a sample set of the larger population is not inclusive enough, representation of the full population is skewed and requires additional sampling techniques. Marketing Essentials.

Major advantages include its simplicity and lack of bias. Among the disadvantages are difficulty gaining access to a list of a larger population, time, costs, and that bias can still occur under certain circumstances.

Random Sample: What's the Difference? Partner Links. Related Terms How Simple Random Samples Work A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.
A simple random sample is meant to be an unbiased representation of a group. Representative Sample is often used to extrapolate broader sentiment A representative sample is used in statistical analysis and is a subset of a population that reflects the characteristics of the entire population. Sample A sample is a smaller, manageable version of a larger group.
Samples are used in statistical testing when population sizes are too large. Reading Into Stratified Random Sampling Stratified random sampling is a method of sampling that involves the division of a population into smaller groups known as strata. The Ins and Outs of Systematic Sampling Systematic sampling is a probability sampling method in which a random sample from a larger population is selected. Sampling Definition Sampling is a process used in statistical analysis in which a group of observations are extracted from a larger population.

Convenience Samples for Research
Posted in Customer Engagement. Face it: censuses are expensive. If we want to project from the results of a survey to our target audience with a knowable margin of error, we use random or probability sampling, which provides for equal opportunity for selection, with external selection of any member of the target population. Getting representative results — results that can extrapolated back to the target population — is not always a research objective. Surveys fielded to convenience samples have many of the advantages of surveys in general, which is why the sampling technique is so widespread. The decision to use a convenience sample instead of a probability sample is often driven by cost. Did you like this story?
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.
Convenience sampling also known as grab sampling , accidental sampling , or opportunity sampling is a type of non-probability sampling that involves the sample being drawn from that part of the population that is close to hand. This type of sampling is most useful for pilot testing. A convenience sample is a type of non-probability sampling method where the sample is taken from a group of people easy to contact or to reach. For example, standing at a mall or a grocery store and asking people to answer questions would be an example of a convenience sample. This type of sampling is also known as grab sampling or availability sampling. There are no other criteria to the sampling method except that people be available and willing to participate. In addition, this type of sampling method does not require that a simple random sample is generated, since the only criterion is whether the participants agree to participate.
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.
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.

CONVENIENCE SAMPLING: DEFINITION, APPLICATIONS, ADVANTAGES, METHOD, AND EXAMPLES
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.
Convenience sampling also known as availability sampling is a specific type of non-probability sampling method that relies on data collection from population members who are conveniently available to participate in study. Facebook polls or questions can be mentioned as a popular example for convenience sampling. Convenience sampling is a type of sampling where the first available primary data source will be used for the research without additional requirements. In other words, this sampling method involves getting participants wherever you can find them and typically wherever is convenient. In convenience sampling no inclusion criteria identified prior to the selection of subjects. All subjects are invited to participate.
The key disadvantage of convenience sampling is that the sample lacks clear generalizability. Moreover, these advantages and disadvantages apply, albeit in.
