A questionnaire is a set of written questions for data collection, while an interview involves direct, often verbal interaction to gather information.
Questionnaire vs. Interview

Key Differences

A questionnaire is a structured set of questions designed for written responses, often used in surveys or research. An interview, on the other hand, is a more interactive process where questions are asked verbally by an interviewer to an interviewee, facilitating a two-way conversation.

Questionnaires are typically written and can be conducted without direct interaction, enabling anonymous and unbiased responses. Interviews involve verbal communication, allowing for more in-depth and nuanced responses, and often include non-verbal cues like body language.

Questionnaires are used to gather quantitative data from a large audience efficiently. Interviews are more qualitative, seeking detailed insights, opinions, and explanations, often used in research, journalism, and employment processes.

Questionnaires have a fixed set of questions, limiting adaptability based on respondent feedback. Interviews, conversely, offer the flexibility to adapt questions, delve deeper into topics, and clarify responses in real time.

Responses from questionnaires are easier to quantify and statistically analyze due to their structured nature. Interview responses require more complex interpretation, considering the nuances of verbal communication and the context of each answer.
