Quizplus · Accepted Answer

The formal experiment is the best research technique to support or refute the hypothesis that anxiety causes poor test performance because it allows the researcher to manipulate the independent variable (anxiety) and measure its effect on the dependent variable (test performance) while controlling for extraneous variables. This will provide the most rigorous testing of the hypothesis and allow for causal inference. The other methods, such as the descriptive method, clinical method, or correlational method, may be useful for exploring the relationship between anxiety and test performance, but they do not provide the same level of control and manipulation as a formal experiment.
