What is one advantage of using questionnaires for data collection?

Using questionnaires for data collection offers the significant advantage that responses can be compared among respondents. This comparability is critical for analyzing trends, behaviors, and opinions across a larger population. When questionnaires are designed with standardized questions, it allows for uniform data collection. This means that the responses can be quantitatively analyzed, providing insights into patterns that may emerge from the data.

Additionally, the ability to compare responses facilitates statistical analysis, enabling researchers to draw conclusions based on the aggregated data and to identify correlations or differences among various demographic groups. This can enhance the reliability and validity of the research findings, making questionnaires a powerful tool in various fields of study such as social sciences, health research, and market analysis.

On the other hand, conducting questionnaires is generally not expensive compared to other methods, such as in-depth interviews or focus groups. They also have the potential to reach a much larger audience, rather than being limited to smaller sample sizes. While immediate feedback may be desirable, it is not a predominant advantage of questionnaires, as the feedback usually isn't instantaneous unless designed for real-time responses.
