Which scientific method of research would be used if a college student running for student body president was trying to determine whether to emphasize campus security, improved parking facilities, or increased health services in their campaign?

The correct approach will be "a survey".

Explanation:

The survey is characterized mostly as a polling tool being used to receive data from a clearly-programmed community of constituents to obtain knowledge and insight into different relevant topics. Surveys, therefore, have a range of goals that could be conducted out in various ways, based mostly on the opportunity to analyze as well as the aims to be accomplished.
