Question

Among types of research, only _______ can establish causality.
A. random surveys
B. experiments
C. representative surveys
D. biased studies

Answer 1

Answer: Option B experiments

Explanation:

• Causality is also known as causation or cause and effect. It is defined as the relationship that exists between cause and effect.

• Among types of research the experiments produce an outcome and have a cause and effect and thus can establish causality.

• As compared to experiments , the biased studies as the name suggests are biased in nature and thus cannot establish a causality.

• Similarly, random and representative surveys are slightly biased in nature and not correct.

Since the experiments have a cause and effect, they can establish causality.
