What is the primary objective of using sampling in research?

The primary objective of using sampling in research is to make judgments about a larger group based on the analysis of a smaller subset. This process allows researchers to draw conclusions about a population without needing to survey every individual within that group. By selecting a representative sample, researchers can effectively generalize their findings and insights to the broader population, ensuring that the results maintain external validity.

Sampling is also associated with efficiency and practicality, as it enables researchers to gather data and conduct analyses more quickly and at a lower cost than a full population study. While reducing costs and creating a large database may be benefits of sampling, the main focus remains on the ability to accurately represent and infer insights about the larger group based on the sampled data. Eliminating all bias can be an important goal in research design, but it is often a more complex and challenging aspect that may not be fully achievable even with sampling techniques.
