Which is a strength of questionnaires?

• A. They always prove causation
• B. Cost effective
• C. They require no planning
• D. They cannot gather data quickly

Answer: (B)

A major strength of questionnaires is their cost-effectiveness. They can be distributed to large numbers of people with relatively little expense, especially when delivered online or by mail. This reduces the need for many interviewers, long interviewer time, and travel, while still producing standardized responses that are easy to compare across participants. Because you can collect data from many respondents in a short period, questionnaires are ideal for surveys aiming to identify broad patterns in attitudes, beliefs, or behaviours. In terms of the other statements, questionnaires don’t prove causation—they’re typically correlational. They also require careful planning and design to avoid bias and ensure reliability and validity. And they can be used to gather data quickly, particularly online, so the idea that they cannot gather data quickly isn’t accurate.
