Descriptive research methods are pretty much as they sound — they describe situations. They do not make accurate predictions, and they do not determine cause and effect. There are three main types of descriptive methods: observational methods, case-study methods and survey methods.
Also asked, why is descriptive research used?
Descriptive research is used to describe characteristics of a population or phenomenon being studied. Hence, descriptive research cannot describe what caused a situation. Thus, descriptive research cannot be used as the basis of a causal relationship, where one variable affects another.
What is the purpose of a descriptive study?
Descriptive studies are observational studies which describe the patterns of disease occurrence in relation to variables such as person, place and time. They are often the first step or initial enquiry into a new topic, event, disease or condition.
What is the purpose of explanatory research?
We began exploring something new with exploratory research. Then, we conducted descriptive research to increase our knowledge of it. Lastly, we need to explain it. Explanatory research is defined as an attempt to connect ideas to understand cause and effect, meaning researchers want to explain what is going on.
