The parametric test one way ANOVA was used to analyse the significance of listening time since it was normally distributed (Shapiro-Wilk W=0.926, p>0.05). The study found that there were significant effects of participant (F(2,25)=5.017, p=0.015) on listening time. But the significant effect of question (F(3,24)=0.037, p=0.990) on listening time was not found. The average listening time is shown in Fig 6.
