Statistics
In the first stage of the data analysis, basic descriptive statistics were compiled. Then normality of distribution was tested using the Shapiro–Wilk test. Due to the lack of normality, non-parametric Friedman test were used. Since the Friedman test showed there is a significant difference between the groups, we use the Nemenyi test to determine which groups are significantly different. Furthermore, the similarity of groups was studied by hierarchical cluster analysis based on the Euclidean measure with the complete method and the results were presented on a dendrogram. All calculations, statistical analyses and figures were performed using the R software version 4.2.2 (R Core Team, 2022)
