2.6. Data Analysis
Quantitative data were summarized as mean (standard deviation), and qualitative data were given as numbers (percentages). Pearson’s Chi-square test was utilized to examine the differences among the categories of categorical variables. When significant differences were detected, the Bonferroni corrected Pearson’s Chi-square test was also used for pairwise comparisons. A p-value of 0.05 was considered statistically significant. IBM SPSS Statistics 26.0, IBM SPSS Modeler 18.0, and RapidMiner Studio Educational Edition 9.8 softwares were used for the analyses (17, 20, 21).
