Further, the paired t-test was applied to compare the imply prior to and soon after regarding normality assumption, when Wilcoxon test was made use of for lack of normality in the data gathered. Also, within the case of nominal variables identified inside the qualitative findings, chi-square together with cohen’s d for impact size had been employed.
