What is one of the objectives of sampling in research?

One of the primary objectives of sampling in research is to ensure representativeness. This means that the sample selected should accurately reflect the characteristics of the larger population being studied. By achieving representativeness, researchers can generalize their findings from the sample to the broader context, allowing for more valid and reliable conclusions.

When a sample is representative, it captures the diversity and variations within the population, which is essential for making inferences and validating research hypotheses. This becomes particularly important in fields such as social sciences, health studies, and market research, where the goal is to draw conclusions that apply to a wider group.

In contrast, the other options are not aligned with the main objectives of effective sampling. Maximizing observer bias would negatively affect the integrity of the research, minimizing data collection effort might compromise the depth and quality of the data gathered, and focusing on small sample sizes can lead to issues with variability and generalizability. Therefore, ensuring that the sample is representative is fundamental to the credibility and applicability of research findings.
