A recent research study of undergraduate students analyzed the effects of music on human emotions. Each of the 200 participants

attended at least 1 two-hour concert of classical music per week over the course of 12 weeks of their spring semester. At the end of the experiment, all of the students filled out a questionnaire assessing their emotional state. Based on the results of the questionnaires, all of the 10 students who attended the greatest number of concerts reported lower stress levels and higher satisfaction with their lives. Also, most of the 20 students who attended the fewest number of concerts reported below-average levels of emotional comfort.
Which of the following must be true based on the evidence presented above?
(a) Most of the 200 participants improved their emotional state and lowered their stress levels.
(b) During each week of the experiment, the participants spent at least 2 hours less on their academic work as a result of concert attendance.
(c) Listening to classical music for at least 2 hours per week improves the emotional well-being of the majority of young adults.
(d) More than 6 participants attended at least 14 concerts during the course of the experiment.
(e) At least some of the students participated in the study in order to gain free access to classical concerts.

The most straightforward case of an experimental research is leading a laboratory  test. For whatever length of time that examination is being directed under logically satisfactory conditions – it qualifies as a trial explore. A genuine experimental research is thought to be fruitful just when the scientist affirms that an adjustment in the dependent variable is exclusively because of the control of the independent variable.
