A common disadvantage of open-ended questions is:

• A. Some responses may not be relevant to your research
• B. All responses are easily categorized
• C. They are always easy to analyze
• D. They produce uniform answers

Answer: (A)

Open-ended questions give rich, detailed information because people can express their thoughts in their own words. But a common drawback is that some responses may not be relevant to what you’re trying to find out. Since respondents interpret questions in different ways and may share experiences or opinions that don’t directly address the research aims, you end up with data that doesn’t help answer the question.

This makes analysis more challenging: you have to read through many varied answers, decide which ones are useful, and then group similar ideas into themes. That process can be time-consuming and introduces subjectivity, which can affect reliability and comparability across respondents. In contrast, if you need clear, comparable results, closed questions are easier to categorize and analyze.

So the main point is that the depth and flexibility of open-ended questions come at the cost of potential irrelevance in some responses, which complicates processing the data.
