Evaluation of the statistical significance between mean ranks of different parameters of two groups were performed using Mann-Whitney U test
Table 4 shows the mean ranks of each of the five skills found to be significant through the Mann-Whitney U test

As seen in the Table 1, the Mann-Whitney U test
results show that the fluent writing levels of the 5th and 6th grade pupils differ significantly depending on whether they are placed in setting with or without music (U=69,500, p<.
