A Telephone survey is survey conducted over the telephone system and is a flexible research method, particularly in consumer research
[edit] Aspects
- use of interviewers encourages sample persons to respond, leading to higher response rates.[1]
- interviewers can increase comprehension of questions by answering respondents' questions.
- fairly cost efficient, depending on local call charge structure
- good for large national (or international) sampling frames
- cannot be used for non-audio information (graphics, demonstrations, taste/smell samples)
- three types:
- traditional telephone interviews
- computer assisted telephone dialing
- computer assisted telephone interviewing
- Mail
- response rate 5% - 30%[citation needed]
- the questionnaire may be handed to the respondents or mailed to them, but in all cases they are returned to the researcher via mail.
- cost is very low, since bulk postage is cheap in most countries
- long time delays, often several months, before the surveys are returned and statistical analysis can begin
- not suitable for very complex issues
- no interviewer bias introduced
- large amount of information can be obtained: some mail surveys are as long as 50 pages
- response rates can be improved by using mail panels
- members of the panel have agreed to participate
- panels can be used in longitudinal designs where the same respondents are surveyed several times
