(b) What is the weight for attribute D? (c) Answer the two questions above if Jill decides that attribute D has the same importance as J, but all other scores stay the same.
What will be an ideal response?
(a) S = 1 + 2 + 3 +… + 10
= n(n+1)/2
= 10(11)/2
= 55
(b) WD = 4/55 = 0.073
(c) S = 1 + 2 + 3 + 10 + 5 + … + 10
= 61
WD = 10/61 = 0.164
