It's easy to score closed questions as quantitative data, because the researcher knows all the possible answers in advance. More complicated closed questions can be multiple-choice questions. The simplest type of closed question is a 'Yes/No' question. Closed questions only allow an answer from a list of responses.The advantage is that the respondent doesn't have to feel restricted about how they answer, but it can be very difficult to score or compare the qualitative data you get from open questions. The best open questions encourage longer answers and begin with words like ' How' and ' Why' - questions beginning with ' What' and ' When' tend to produce limited answers. Open questions allow the respondent to answer in any way they like.However, there are different types of question that can be asked: Unlike interviews, questionnaires are always structured - the questions have to be written in advance. They can be transcribed (written down) later and analysed in detail. Interviews are often recorded (either audio-only or filmed). They aim to get 'the best of both worlds' (the validity of unstructured interviews and the reliability of structured interviews) but they are difficult to do: the interviewer has to be well-trained or quite experienced. Semi-structured interviews contain pre-determined questions but also feature informal chat - they sound and feel more realistic than structured interviews.The main advantage is that lots of participants can be interviewed this way and their responses easily compared. they are reliable) but they are stilted and unnatural (i.e. Structured interviews always feature the same questions in the same order (i.e. Structured interviews have pre-determined questions - they don't sound or feel much like a normal conversation.

The big advantage is that the interviewer can stop and pursue an interesting line of conversation or go back over questions that weren't answered clearly. they are valid) but no two unstructured interviews will be exactly the same (i.e.

Unstructured interviews put the interviewee at ease and produce natural responses (i.e.

Unstructured interviews are apparently informal chats - but there's still a purpose behind them.

This usually takes the form of the interviewer asking questions and the interviewee answering them - but sometimes the interviewee might ask questions or the interviewer might offer instructions, clarifications or responses of their own. What makes an interview different from a questionnaire is that the interviewer is contributing at the same time as the interviewee. Interviews are usually face-to-face conversations (although they can take place over a telephone or over social media).
