Do not know who responded. Requires highly structured questionnaire with predominantly closed-end questions. MAIL QUESTIONNAIRES

TYPES OF INTERVIEWS Structured Interviews – the interviewer uses an interview sequence with predetermined questions that are asked in exactly the same way. Semi-structured Interviews – the researcher follows a predetermined structure and direction, but can ask related, unanticipated questions that were not originally included. Unstructured Interviews – the researcher does not follow an interview sequence and elicits information by engaging the interviewee in a free and open discussion on the topic of interest.

20 Hair, Babin, Money & Samouel, Essentials of Business Research, Wiley, 2003. Semi-structured interviews that use an exploratory research design and are considered qualitative research. Informal discussions among 8 to 12 respondents that share something in common. Guided by a moderator who encourages discussion and keeps the group “on track”. Random samples are not required.

23
23 Hair, Babin, Money & Samouel, Essentials of Business Research, Wiley, 2003..... also referred to as “in-depth” interviews, they are an unstructured one-to-one discussion session between a trained interviewer and a respondent who has some specialized insight. DEPTH INTERVIEWS

Expensive in terms of time to complete the process: need to gain access. training of interviewers. co-ordination and supervision of fieldwork. time for interview. Unlikely to be used with large samples. Problem of lack of anonymity. Opportunity to probe complex questions. Opportunity to record additional information. PERSONAL INTERVIEWS

If questions are open-ended, make sure question does not exceed 15 words; interviewee should not be expected to give lengthy answers. For closed-end questions the number of pre-coded options should not exceed five. Response rates can be a problem. Low cost form of personal interviewing. Obtain information quickly. More costly than mail questionnaires but less than personal interviews. Administration relatively easy. Interview bias less of a problem. Problem with unlisted numbers. TELEPHONE INTERVIEWS:
