Step-by-step explanation:
The type of study a researcher is using if he asks a grandparent about their experiences during the Great Depression is a qualitative study. Qualitative research is an exploratory and interpretive form of inquiry that focuses on understanding the meaning and experiences of individuals, rather than just quantifying and measuring data. In this case, the researcher is interested in gaining a deeper understanding of the personal experiences and perspectives of the grandparent during the Great Depression, and how it has affected their life. Qualitative research methods, such as in-depth interviews and observations, are often used to collect data in this type of study.
