|Computer-aided telephone interviewing (CATI) is an automated form of survey research that
utilizes computers and telephone technology to collect data from respondents
||Computer-assisted personal interviewing (CAPI) is a type of survey method where questions are
posed to respondents using a computer-based program
|Conducted entirely by phone, often with a prerecorded script and multiple choice responses
||Conducted face-to-face with trained researchers, usually in the respondent’s home or place of
|Typically less expensive than CAPI because there are fewer labor costs and the interviewer does
not need to travel and time-saving
||More expensive than other survey methods due to the cost of travel and equipment and is time
|Usually have a predetermined set of questions that must be followed, making it difficult to
adjust them during data collection.
||More flexibility for researchers as the interviews can be adapted to different contexts and made
|Have the benefit of reaching a large number of people quickly and at a relatively low cost.
||Used in developing countries or in remote areas where access to technology is limited
|Mainly used for quantitative research, making it difficult to collect qualitative data.
||Used to collect qualitative data as well as quantitative data
|More efficient for collecting numerical data, but cannot capture nonverbal cues.
||Enables researchers to measure nonverbal responses, such as facial expressions and body language
|Calls are usually prerecorded and the interviewer does not have much control over how the
questions are asked
||Allows for greater control over the interview process, meaning that the interviewer can set the
pace and control the flow of the conversation
|Surveys cannot be audio-recorded, so any mistakes or misheard responses cannot be identified.
||Interviews can be recorded for later review by researchers or used to verify answers given by
|Does not allow for the use of multimedia or other visual aids.
||Allows for the use of multimedia such as pictures and videos to supplement the interview
|CATI interviews are usually conducted in one language, and translations may be required to reach
a wider audience.
||CAPI can be used in a variety of languages, making it easier to reach international respondents
|Effective for large-scale projects due to the cost savings associated with automated
|| Can be used for both small-scale and large-scale surveys
|Suitable for quantitative data collection, as the interviewer does not have much control over
the conversation flow.
||Suited for surveys that require in-depth probing and open-ended questions
