Question

Quizplus · Accepted Answer

The best way to determine whether playing classical music while studying has a positive effect on test scores is through conducting an experiment. This would involve a controlled study where one group of participants listens to classical music while studying and another group studies without any music. Test scores of both groups can then be compared to determine if there is a significant difference in scores between the two groups. This method allows for a clear cause-and-effect relationship to be established between music and test scores. Introspection and asking a single person who gets good grades may not necessarily provide a representative sample, and a survey may not allow for control over confounding variables.
