sorting coefficient

[′sȯrd·iŋ ‚kō·i‚fish·ənt]
(geology)
A sorting index equal to the square root of the ratio of the larger quartile (the diameter having 25% of the cumulative size-frequency distribution larger than itself) to the smaller quartile (the diameter having 75% of the cumulative size-frequency distribution larger than itself).

After consideration and testing these indicators, we suggested below ranking for them: Physical resistance with the weight( value) of 0/127 was in the first grade, GFN with weight of 0/125 was in second grade, permeability with the weight of 0/122 was in the third, Round corner with the weight of 0/120 was in the fourth, Specific surface area with the weight of 0/106 was in the fifth, Thermal conduct with the weight of 0/096 was in the sixth, expansion with the weight of 0/086 was in the seventh , with the weight of 0/084was in the eighth , Humidity percent with the weight of 0/074 was in the ninth and Sorting coefficient couple with the weight of 0/055 was tenth.
