Question

Quizplus · Accepted Answer

Experiments are the only research designs that allow researchers to establish cause and effect relationships. In an experiment, the researcher manipulates an independent variable and measures its effect on a dependent variable while controlling for other variables. This allows for the isolation of the specific cause of the observed effect. Other research designs such as naturalistic observation and correlational techniques can only establish relationships between variables but cannot determine causality.
