What marketing course falls under STEM in the USA? 

In the USA, marketing courses typically fall under the category of business and management rather than STEM (Science, Technology, Engineering, and Mathematics) as they are not considered to be part of the traditional STEM fields.

However, some aspects of marketing, such as data analytics and market research, may incorporate STEM principles and techniques. For example, courses in marketing analytics or marketing research may include elements of statistics, data science, and programming.
