Explanation:

Questionnaire is only a set of questions that researchers could give the people in order to obtain a certain qualitative or quantitative data. Typically, the researchers use closed ended questions that can easily be answered by the people.

Example of questions in questionnaires:

- Do you enjoy using X product ? Yes/No

- Are you employed ? Yes/No

Surveys on the other hand utilize questions that specifically designed for further analyzation using specific set of criteria. Typically, researchers use open ended questions that make the answer of the questions be a little bit more complicated

Example of questions in surveys:

- What was your first thought when you first using the product?

- Why do you think it is difficult for you to obtain a job?
