| Total square ranging deviator | 1,849 | 1,089 | 729 | 64 | 361 | 36 | 2,025 | 676 | 9 |
| Coefficient (W) | 0.79 | =12*6,838/[12^2*(9^3–9)] | |||||||
| Significance of the concordance coefficient | 75.98 | =12*6,838/(12*9*10) | |||||||
| Rank of table concordance | The null hypothesis H0: The consent of experts in rankings is not accepted. Degrees of freedom (df) are v = 9 - 1 = 8, which is # of categories minus 1. The indication is 75.97 > 15.5 at α = 5% | ||||||||
| Compatibility of expert judgment | Hence, we can reject the null hypothesis H0. | ||||||||
