Question

Quizplus · Accepted Answer

The experimental method is the best choice for determining cause-and-effect relationships between variables. This method involves manipulating one variable (independent variable) while controlling all other variables, and then measuring the effect on another variable (dependent variable). This allows the scientist to determine whether changes in the independent variable are causing changes in the dependent variable, therefore establishing causality. The other methods listed (clinical, correlational, and survey) are not designed to establish causal relationships between variables.
