The purpose of sampling techniques in research is primarily to collect samples in an objective and reliable manner. This approach enables researchers to gather data that accurately represents a larger population without needing to test every individual. By utilizing systematic sampling methods, researchers can minimize bias and error in their data collection, leading to more valid and generalizable results.

Objectivity in sampling is crucial, as it helps ensure that the findings of a study are reflective of the population being studied, rather than being skewed by the specific characteristics of the sampled individuals. When samples are collected reliably, researchers can confidently draw conclusions and make inferences about the entire population based on their analysis of the sample data. This reliability enhances the credibility of research findings and supports effective decision-making based on those results.
