Explanation:
1. Exploratory research clarifies the nature of the problem to be addressed. It is a preliminary research undertaken before additional research is conducted.
2. Descriptive research describes the situation of a problem by asking how, what, where, and where questions instead of focusing on “why” a particular phenomenon occurs.
3. Causal research (or experimental studies) determines whether a variable or more variables cause or affect the values of other research variables. It traces the cause and effect of a phenomenon.
