It was observed that all comparisons revealed a statistically significant difference between the moments, using the Wilcoxon test, demonstrating an improvement in the percentage of correct consonants in all tests and in the mean of the CCP (Table 3).
However, only the Wilcoxon test reveals statistically significant differences (10% level).
Student's t, Z and Wilcoxon tests were used to compare both groups through parametric quantitative, parametric qualitative and nonparametric variables, respectively, where [less than or equal to] 0,05 p values were considered to be significant.
