What is a significant advantage of using the questionnaire method?

Using the questionnaire method offers a significant advantage in that it is quick and simple. This method allows researchers to gather information from a large number of respondents in a relatively short amount of time. Questionnaires can be administered in various formats, such as online, by mail, or in person, which can further streamline the data collection process. The straightforward nature of structured questions means that they can be answered promptly by respondents, leading to efficient data collection.

Additionally, because questionnaires can be designed to be easily understood, they eliminate the need for extensive training or skills for those administering them, making the process even more efficient. This contrasts with methods that require extensive personal interviews, which can be time-consuming and demanding in terms of resources and retraining. Therefore, the speed and simplicity inherent in using questionnaires make this method particularly advantageous for collecting large datasets rapidly and cost-effectively.
