This research found that even though data was not normally distributed, the data still had the same variances. Therefore, the independent t-test in this research used Wilcoxon Signed Rank Test. The results discovered that the t value was 0.030 which was lower than 0.050. It indicated that the treatment was significantly effective in this research.
