 Central location tests (CLT) are conducted under a controlled environment at any hall. This method helps in interacting with the participant in person. Also, it helps in gathering quick market feedback. 

 While conducting face-to-face interviews, a researcher directly communicates with the participant. Then the prepared questionnaires are asked to the participant to garner factual information and any other information that will help generate an accurate report.
