In trying to improve the techniques I use in the classroom and reduce the anxiety of the students, I decided to try an experiment.I decided that I would incorporate more relaxation techniques prior to exams. For a comparison, I subjected the students to twice the exams.In essence, I did a pre-test and post-test.The scores are below.At = 0.05, can it be concluded that the relaxation techniques helped improve test scores?
