【正确答案】 B、C

【答案解析】Interview is a form of research method which involves interaction between interviewer and respondents working through standardized questionnaires. As for standardized questionnaires, they refer to structured interview that is favored by positivists, or through informal conversation which refers to unstructured interview favored by phenomenologists. First of all, interview can be carried out either individually or in group. Individual interviews allow in-depth discussion of the research topic, especially topics concerning sensitive issues as it is easier to establish rapport between the researcher and respondent. However, individual interviews are more suitable for small scale study as it is rather time consuming. Although group interviews are not suitable for research of sensitive topics, it however allows research topic which is carried out in a group context to be studied. It allows larger sample size to be studied in a shorter time than in individual interview. Hence, data collected in group interview will be more representative and generalizable.
