a Kendall’s tau b coefficient is a statistic used to measure the association between two quantities. In this table, positive values indicate poor perception as we vertically advance to independent variables’ categories and vice versa for the negative values. Level of significance < 0.1; * Level of significance < 0.05; ** Level of significance < 0.01.
