A researcher was interested in the emotional effects of music on exam performance. Before their exam, a professor took one group of students into a room in which calming music was played. A different group of students were taken to another room in which new wave hard rock was being played. The students then took the exam and their scores were reported. What type of analysis would be most appropriate

Independent (unpaired) t-test

In research methods, the term "independent (unpaired) t-test" is described as a process that is being used by the researcher or the investigator when two different sets of identically distributed and independent samples are being obtained and henceforth "one from each of the two" different populations are being compared or analyzed. Therefore, according to the given scenario, the researcher or the investigator discovers two different "independent samples" and utilizes the "unpaired type of the t-test".

In the question above, the most appropriate analysis would be independent (unpaired) t-test.
