Both methods can provide extremely accurate results. The Experimental method allows the researcher to have great control over how the experiment is given. The survey method is accurate because it lets the researcher to get the thoughts and opinions of a much larger sample population.

Because of the experimental method's artificial setting, the results may not reflect what would happen in the "real world."

With a hypothesis that frustration leads to aggressive behavior, the experimental method would probably show the best, most accurate results.

The independent variable is the factor that is being changed and tested by the investigator. The independent variable in the aggressive behavior experiment would be whether or not the sample or subject is frustrated.

The dependent variable is the factor being measured by the investigator. In this experiment, the investigator could put the subject through a frustrating task (manipulating the independent variable); the investigator would then measure the difference in the amount of aggression in the person when he/she was frustrated and when he/she was calm.
