Central location test, sometimes referred to as spot test, are conducted among consumers at a designated facility such as a shopping mall. Participants typically are recruited while in a mall to take part in a product test, such as a teste test of a new sift drink. Alternatively, consumers can be recruited, usually by telephone, to come to a central location to participate in a research project (Crask Melvin, et al. 1995)
Sigma Research provides the method of Central Location Test (CLT). This data collection method is in a strategic place to get the target respondents in bulk, such as malls, markets, campuses, or office locations.
