Final answer:
CATI systems offer cheaper, faster, and better-quality data transmission, enhancing the efficiency and accuracy of telephone-based surveys by direct data entry.
Step-by-step explanation:
An advantage of using a computer-assisted telephone interview (CATI) system to collect data is that it allows for cheaper, faster, and higher quality data transmission. Since the interviewer enters the respondent's answers directly into the computer program, it reduces the likelihood of human error in data entry.
Moreover, the use of CATI can address some of the challenges associated with telephone polling, such as dealing with unlisted and cellular numbers through random-digit-dialing (RDD), increasing the representativeness of the survey results. However, it's important to note that errors can occur if the interviewer inputs incorrect answers or reliability issues arise if they deviate from the script.
