Computer-Aided In-Person Interviews
In some studies it is very difficult to find survey respondents who are members of some population. For example, there may not be a good list of people who have purchased a specific item from a retailer in a particular market. Or, it may be difficult to contact someone who has used services at a community clinic in a city, for example. In these instances, we may want to take the survey to the locations on portable computing devices and administer questionnaires on the spot with individuals who have just purchased, or just used, the products and services.
