What can qualitative research primarily help to explore?

Qualitative research is primarily utilized to delve into human experiences and perspectives. This type of research focuses on understanding the meaning behind individuals' thoughts, feelings, and behaviors through methods such as interviews, focus groups, and observations. It allows for a deep exploration of the context and nuances of participants' experiences, which can uncover insights not captured by quantitative research methods.

In contrast, other options involve different aspects of research. Quantitative metrics and statistical data are typically the domain of quantitative research, which is centered on numerical data and measurable variables. Causal relationships are also primarily explored through quantitative methods, which seek to identify and establish relationships between variables, often through experiments or statistical analyses. Qualitative research does not aim to establish generalizable causal relationships but rather to provide a rich, detailed understanding of individual or group experiences. Thus, it is best suited for exploring the complexity and diversity of human experiences and perspectives.
