Descriptive design is a type of quantitative research design that tends to describe/depict the current status (condition) of a particular variable or phenomenon. In the case above, the research is quantitative because it deals with quantifiable data, which is the frequency of scrub cases. Vincent was trying to describe the frequency of scrub cases between the north and south affiliated hospitals of their school, which makes it a descriptive design.
