Dr. Smith is curious if teaching students a relaxation technique will reduce their test-taking anxiety. the best research method to evaluate this phenomenon is an Experimental Method.
An experimental method refers to a scientific method in which variables are manipulated and studied to establish cause and effect relationships.
It proceeds in several steps. The researcher will formulate a hypothesis regarding the object of his study. Then, the cause or independent variable is manipulated and the effect or dependent variable is measured. This is done within a controlled environment, so there is little to no effect of external factors.
In the above case, Dr. Smith may formulate a hypothesis that certain relaxation techniques will reduce the test-taking anxiety of students.
He will teach the technique (independent variable) to the students and observe if there is a subdued effect on their stress levels (dependent variable). If that is the case, his hypothesis has been scientifically confirmed.
