Which is an advantage of using questionnaires for research?

Using questionnaires for research offers a significant advantage in that they can be effectively distributed to a large number of participants. This ability to reach a wide audience is crucial for gathering diverse opinions and obtaining a comprehensive understanding of the subject being studied. When a researcher deploys a questionnaire, they can quickly collect data from thousands of respondents, which can enhance the overall validity and reliability of the results.

This method allows for quantitative analysis, enabling researchers to identify trends, patterns, and correlations within large datasets. The scale at which questionnaires can be administered makes them particularly useful for studies requiring significant generalization of findings across broad populations. Furthermore, the cost-effectiveness and efficiency associated with online or paper-based questionnaires can also support large-scale research initiatives by minimizing the resources needed to collect data from many individuals.
