Step-by-step explanation:
The primary advantage of mixed mode surveys is that researchers can take the advantages of different modes to achieve their data collection goals.
Mixed mode surveys allow researchers to use multiple methods of data collection, such as online surveys, phone interviews, and mail surveys, to reach a wider audience and increase response rates. By combining different modes, researchers can overcome the limitations of each individual mode and gather more comprehensive and accurate data.
