Bekvemmelighedsudvælgelse

Bekvemmelighedsudvælgelse, often translated as convenience sampling or accidental sampling, is a non-probability sampling technique where subjects are selected because of their convenient accessibility and proximity to the researcher. This method involves choosing individuals who are readily available and easy to reach, without considering whether they are representative of the larger target population.

The primary advantage of bekvemmelighedsudvælgelse is its simplicity and cost-effectiveness. Researchers can gather data quickly and with minimal effort, making it a popular choice for exploratory studies or pilot research where a statistically rigorous sample is not the main objective. It can be useful for generating initial hypotheses or for gathering preliminary insights.

However, bekvemmelighedsudvælgelse suffers from significant limitations. Because the sample is not selected randomly, it is highly susceptible to selection bias. The individuals included in the sample may possess characteristics that differ systematically from those not included, leading to findings that cannot be generalized to the broader population. This lack of representativeness undermines the external validity of the research. Consequently, results obtained through bekvemmelighedsudvælgelse should be interpreted with caution, and it is generally not recommended for studies aiming to make definitive conclusions about a population.
