Correct Answer:
Option D —
Normal-Disguised Questionnaire
In research methodology, the classification of questionnaires is based on two main criteria:
Structure: How formal and predetermined the questions are.
Disguise: Whether the true purpose of the research is revealed to the respondent.
Why this is the correct choice:
The standard academic classification includes four specific combinations:
Structured-Undisguised: The most common type; questions are fixed and the purpose is clear.
Structured-Disguised: Questions are fixed, but the purpose is hidden to prevent bias.
Unstructured-Undisguised: Open-ended questions where the purpose is explained.
Unstructured-Disguised: Open-ended questions where the purpose is hidden (often used in depth-psychology or projective tests).
"Normal-Disguised" is not a standard category in marketing or social research terminology.
