Question

The great weakness of questionnaire design is lack of ________.

• A. precision
• B. accuracy
• C. theory
• D. consensus

Hint:

Precision = consistency and exactness in responses; questionnaires often trade precision for breadth of coverage.

Answer 1

The Correct Option is A

Step 1: Understanding the limitation.
While questionnaires can collect large amounts of data efficiently, they often lack precision in measurement because:
- They rely on self-reports (prone to bias).
- Response options may oversimplify complex opinions.
- Interpretation of questions can vary among respondents.
Step 2: Eliminate wrong options.
- (b) Accuracy refers to closeness to the truth, which can be improved with good design; precision is still inherently weaker.
- (c) Theory: Questionnaire design is often theory-based, so this is not the main weakness.
- (d) Consensus: Not a core measurement weakness. \[ \boxed{(a)} \]
