Step-by-step explanation:
Observations made from roaming the streets of Mumbai are an example of direct perception for marketers. This involves gathering subjective information based on what is seen in a natural setting, which is a fundamental part of qualitative research. Unlike secondary data which is nonreactive and doesn't involve direct contact with subjects, direct perception requires marketers to interact with or observe people and gather data along the way in the subject's natural environment.
