Explanation
★Research that tests hypotheses to explain how and why a phenomenon operates is explanatory research, so that is the answer.
★Explanatory research goes beyond describing to uncover the reasons behind a phenomenon.
★So it tests hypotheses and theories to show how and why things happen as they do.
★Descriptive research only pictures what exists, without explaining the how and why.
★Predictive research forecasts future outcomes rather than explaining underlying causes.
★Since only explanatory research aims at the how and why through hypothesis testing, that is the answer.
