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).
