Since the scores for the novice group are not normally distributed, we cannot run an independent t-test. The Mann-Whitney test is a nonparametric test that does not assume normality, making it suitable for comparing two groups with non-normally distributed data. Therefore, the Mann-Whitney test is the best choice to test for statistical differences between the novice and expert tennis players' pre-competition arousal scores.
