The most common sampling method is the convenience sample: discussion | Evidence Based Practice | Chamberlain College of Nursing
The implications of using a convenience sample for research studies is that the data collected may not be representative of the population as a whole, which can lead to skewed results. This means that any conclusions from the study cannot be generalized beyond the sample and caution should be taken when interpreting and applying findings. Additionally, since such samples are often self-selecting there is a potential risk of bias affecting outcomes due to certain groups being over or under represented in the selection process.
Overall, while convenience samples can provide useful insights they should be used with caution when it comes down to drawing conclusions on larger populations as these could end up being misleading or inaccurate thus making it important exercise due diligence when conducting any form research.
