Which method is used to ensure that research findings can be generalized to a broader population?

Random sampling is a method that enhances the generalizability of research findings to a larger population. By randomly selecting participants from the population, this approach ensures that every individual has an equal chance of being included in the sample. This reduces bias and helps to create a sample that accurately reflects the characteristics of the overall population. As a result, the findings from the study can be more confidently extended to a wider group, making the results applicable beyond just the individuals involved in the research.

In contrast, systematic reviews focus on synthesizing existing research rather than collecting new data, while statistical control refers to techniques for managing confounding variables in analysis. Focused interviews are qualitative methods used to gather in-depth information but do not inherently allow for generalizations to a larger population. Each of these methods serves different purposes within research methodology, but random sampling is specifically designed to enhance the external validity of study findings.
