Actually, the standard array for creatures in the MM is three 10's and three 11's. To get the modifiers, you subtract 11 from any odd ability score and 10 from any even ability score.Winternight said:If I understood the MM correctly the stat there are just for the standard guy. (human equivalent of 10 in each)
Humanoid warriors use the nonelite array of 13, 12, 11, 10, 9, and 8. Advanced creatures use the elite array of 15, 14, 13, 12, 10, and 8. See pages 6 and 7 of the MM.
