1. Personal Interviewing  Personal in-home interview  Mall intercept interviews  Computer-assisted personal interviews

2. Personal In-Home Interviews  Respondents are interviewed face-to-face  Interviewer task is to contact the respondent, ask questions, and record the response

3. Mall Intercept Interviews  Respondents are interviewed face-to-face  Interviewer task is to intercept the respondent while shopping, ask questions, and record the response  Mall intercept interviews are more efficient than personal in-home interviews

4. Computer-Assisted Personal Interviewing (CAPI)  The respondent sits in front of the computer terminal  Answers a series of questions on the computer screen using a keyboard or a mouse  An interviewer is present to guide and assist the respondent during the interview  Various software packages are available for designing computer-based questionnaires  Pocket PC Survey, Opinio 5.1 and EasyQD are some examples of application software used for questionnaire designing  CAPI is used to collect data at shopping malls, conferences and trade shows

5. Mail Interviews  Traditional Mail  Mail Panel

6. Mail Methods  In traditional mail interviews, questionnaires are mailed to preselected potential respondents  A typical mail interview package consists of the outgoing envelope, cover letter, questionnaire, return envelope, and stimuli (display cards, etc.)  Initial task is to obtain a valid mailing list. Lists can be compiled from telephone directories, alumni databases, membership rosters, etc.

7. Electronic Methods  E-mail Interviews  Internet Interviews

8. E-mail Interviews  Much like a traditional mail interview  The questions are either written within the body of the e-mail message or may be attached in form of a text file  E-mailed questionnaire is as good as a manually administered questionnaire  The received questionnaires need to be manually tabulated, coded, and entered for analysis  Legitimacy of the respondent is difficult to ascertain, as anyone having access to an email address can respond
