Numerical scales of factor contribution.
| Numerical scales | Meaning and explanation |
| 1 | Comparing the two factors, the target factor is as important as the comparison factor | 3 | Comparing the two factors, the target factor and the comparison factor are slightly more important | 5 | Comparing the two factors, the target factor and the comparison factor are strongly important | 7 | On comparison of two factors, the target factor and the comparison factor are more strongly important | 9 | On comparison of two factors, the target factor and the comparison factor are extremely important | 2, 4, 6, 8 | The intermediate values reflect an intermediate position of importance | Reciprocals (i.e., 1, 1/3, 1/5, …, 1/9) | The reciprocal number reflects the reverse comparison positions of the above |
