An open-ended question is a question that cannot be answered with a "yes" or "no" response, or with a static response. Open-ended questions are phrased as a statement which requires a longer answer. They can be compared to closed questions which demand a “yes”/“no” or short answer. [1]
A distinction is made between open-ended and closed-ended questions. An open-ended question asks the respondent to formulate his own answer, whereas a closed-ended question asks the respondent to pick an answer from a given number of options. The response options for a closed-ended question should be exhaustive and mutually exclusive. Four ...
The questions are placed one under the other, forming a matrix with response categories along the top and a list of questions down the side. This is an efficient use of page space and the respondents' time. Open-ended questions – No options or predefined categories are suggested. The respondent supplies their own answer without being ...
In a standardized open-ended interview, the same open-ended questions are asked to all interviewees. This approach facilitates faster interviews that can be more easily analyzed and compared. In a closed fixed-response interview, all interviewees are asked the same questions and asked to choose answers from among the same set of alternatives.
The choice of answers to the questions is often fixed (close-ended) in advance, though open-ended questions can also be included within a structured interview. A structured interview also standardises the order in which questions are asked of survey respondents, so the questions are always answered within the same context.

Whereas closed-ended questions require only that the interviewer read the question and marks the appropriate answer, open-ended questions "can require the interview ...
[2] [3] An important open mathematics problem solved in the early 21st century is the Poincaré conjecture. Open problems exist in all scientific fields. For example, one of the most important open problems in biochemistry is the protein structure prediction problem [ 4 ] [ 5 ] – how to predict a protein 's structure from its sequence.
Choosing a research question is an essential element of both quantitative and qualitative research. Investigation will require data collection and analysis, and the methodology for this will vary widely. Good research questions seek to improve knowledge on an important topic, and are usually narrow and specific. [1]
