Question

Quizplus · Accepted Answer

A natural experiment is the best design to study the effects of disasters on survivors because it occurs naturally, allowing for the observation of individuals without manipulating or controlling variables. This provides a more accurate representation of the real-life situation and avoids ethical concerns that may arise from experimental manipulation. A quasi-experiment and double-blind strategy involve some form of manipulation or control, which may not be feasible or ethical in studying disaster survivors. An experiment also involves manipulation of variables, which may not be possible or ethical in studying the effects of disasters.
