Figure 2
A heat map presents pairwise correlation coefficients among the study variables in a matrix format. Both the horizontal and vertical axes display the same set of variables, allowing for direct comparison of the strength and direction of their relationships. Correlations are represented using a colour gradient ranging from dark blue (strong negative correlations) to dark pink (strong positive correlations), with lighter shades indicating weaker associations. Correlation heatmap. Figure 2 presents the correlation matrix, with colour intensity reflecting the strength and direction of the relationships. Dark blue denotes strong negative correlation while dark pink represents strong positive correlation, with lighter colours reflecting weaker associations. Source: Authors’ own work
