Table 2

Two-by-two comparison of the improved “five-scale method.”

Numerical values	Level of importance
4	Factor i is absolutely more important than factor j
2	Factor i is marginally more important than factor j
1	Factor i is equally important than factor j
1/2	Factor j is slightly more important than factor i
1/4	The j-factor is definitely more important than the i-factor
