What is convenience sampling primarily used for?

Convenience sampling is primarily used for early-stage research requiring quick responses because it allows researchers to gather data quickly and with minimal effort. This sampling method involves selecting individuals who are easiest to reach or readily available, rather than a systematic or randomized approach. This can be especially valuable in exploratory research where speed and accessibility are more critical than statistical rigor.

In the context of early-stage research, convenience sampling can help generate preliminary insights or inform further study. Researchers often utilize this method in scenarios where time constraints are significant, and obtaining a large or representative sample is less feasible. While the findings may lack generalizability, they can still provide useful information that guides the direction of more extensive investigations.

The other options relate to aspects that convenience sampling does not primarily address, such as ensuring a representative sample, conducting rigorous experiments, or validating specific research hypotheses, which typically require more systematic sampling methods that offer a higher degree of accuracy and reliability.
