Sampling | Nursing homework help
The convenience sample, a non-probability method of sampling that allows participants to be selected according to their availability and willingness. Because it’s easy to recruit participants, this sampling method is popular in research studies.
The use of a convenience sampling can impact the interpretation and usage of the results. These are some potential problems to be aware of:
- Limitations in generalizability. One of the biggest drawbacks of convenience sampling may be that it is not representative of all the people. Because convenience samples are not randomly selected, it is possible for certain populations to be underrepresented or overrepresented. Therefore, convenience samples may not have the same results as other groups.
- Inconvenience sampling may also lead to biased results. If a researcher chooses to recruit participants from one particular place or location, it is possible for the findings to be biased in favor of the opinions or experiences of those people. Similar to the previous example, findings that are biased toward a group of participants may also be affected if they recruit people with particular interests or characteristics.
- It can be hard to determine a causal relationship among variables. Another drawback of convenience sampling: Convenience samples might not be sensitive to other influences that may affect the relationship between variables.
The generalizability of findings can be limited by the convenience sampling. When interpreting the findings of studies using convenience sampling, researchers should be aware of the limitations.
