Document Summary
There are different types of questions: open ended and closed ended. Closed questions have a limited number of responses alternatives; they are also easier to code. With open-ended questions the respondents are free to answer in anyway they like. Face-to-face interviews: requires that the interviewer and respondent meet to conduct the interview. Telephone interviews: all interviews for large-scale surveys are done via telephone, less expensive than face to- face interview, its had become easier with the advent of cati (computer assisted telephone interview) system.
