Question

Quizplus · Accepted Answer

Experimental design is the best choice for identifying causal relationships as it involves manipulating the independent variable and observing the effects on the dependent variable while controlling for extraneous variables. This allows researchers to establish cause-and-effect relationships between variables. Other designs like case study, epidemiological and correlational designs cannot establish causality due to various limitations, such as lack of control over extraneous variables and inability to manipulate independent variables.
