If you had a successful car repair facility and needed to know more about how frequently your customers came in and whether you were meeting their servicing needs, what kind of research should you do or commission to help address this marketing issue

Descriptive Research

Explanation:

Considering the scenario described above, the correct answer to the question is "DESCRIPTIVE RESEARCH."

This is because Descriptive Research is a form of research that seeks to answer the question of how, what, where, and when. However, it does not answer the question of why and does not involve the direct manipulation of the researcher.

It aims to describe a situation or population under study.

Hence, in this case, the correct answer is "Descriptive Research."
